Cabin tuning Chevrolet Niva. Chevrolet Niva tuning with photo Chevrolet Niva engine compartment

The Chevrolet Niva car is quite popular due to its reliability, excellent cross-country ability and ease of maintenance. However, the appearance and technical specifications given vehicle as standard, not every car owner is satisfied. Therefore, many motorists prefer to do Chevrolet Niva tuning.

Tuning Chevrolet Niva

Any defects in the car Chevrolet Niva can be easily compensated for by tuning possibilities. Absolutely all car models can be remade according to the ideas of the owner.

External tuning Niva usually consists of installing a body kit that improves the car's aerodynamics, aesthetics and comfort. Complete with a body kit, as a rule, there are steps, thresholds, ladders, roof rails, kengurins, spoilers and so on. You can install whole sets of tuning body kits, for example, "Street Rally", "Niagara" and others.

Technical tuning

Technical tuning Chevrolet Niva improves driving performance vehicle and transmission. It is carried out in order to increase the Niva's cross-country ability in off-road conditions, as well as in difficult natural conditions. Currently, there are a number of improvements, there are solutions that can satisfy any need.

Tuning Chevrolet Niva in urban conditions is a smooth ride, no vibrations, lightness of the steering wheel, on-board computer, comfortable seats and so on.

Chevrolet Niva engine tuning

Many motorists tend to install body kits first, but you should start with internal tuning, namely from the engine compartment. By replacing the factory camshafts and pistons, modifying the cylinder head in terms of improving the valve system and gas distribution mechanism, installing high-throughput exhaust systems and light balanced flywheels, a significant increase in the torque and power of the Nivovsky motor can be achieved.

It would not be out of place to install a lightweight flywheel to start and spin the engine much easier. You can replace stock shock absorbers.

To improve the performance of the Chevrolet Niva engine, it is best to carry out chip tuning. Niva's serial engines, which have been chipped, demonstrate performance indicators that really exceed all generally accepted standards. The motor, in the device of which they made quite serious changes, as a result of which the volume of its combustion chamber increased, the mass decreased crankshaft and connecting rods, tuning appeared camshaft and split gear timing drives, even more needs to be improved in the program that controls it.

Installing a kengurin on a Chevrolet Niva

Many tuned Chevrolet Niva are equipped with a kengurin, despite the fact that automakers do not recommend making such changes to the design of this car.

Kengurin will not only make the car more solid, but also help in case of an emergency, however, in a collision with a pedestrian, it poses an increased danger to the latter. The kengurin is installed either on four studs welded from the bottom of the car on the bumper amplifier, or in two holes for attaching the standard protection to the amplifier. Extended bolts are usually sold as a kit with a kengurin.

Rear bumper protection

On the Chevrolet car Niva, it is advisable to install the corners of the rear bumper protection, which are fixed with two bolts to the amplifier in rear bumper.

Interior tuning Chevrolet Niva

You can not ignore the interior of the cabin, because it is he who will constantly surround the driver. There is no limit to the imagination of a car enthusiast - it can be a leather interior with heated seats, car computer, original neon lighting, a stereo system with a subwoofer and other fashionable accessories that are available today at any tuning parts store. As a result of all the upgrades, you will receive a completely exclusive interior that will fully meet your individual preferences.

Especially the effect of the work done is noticeable if you compare the photo of the standard interior and the photo of the Chevrolet Niva tuning.

The heiress of the legendary Niva, Chevrolet Niva, does not claim to be a veteran, however, she has become quite popular model. She was loved for a good design from the Bertone studio, for a comfortable interior, functionality and relatively low cost. Naturally, as befits a decent SUV, Chevrolet Niva is bought as an initial set of spare parts to make it a real and comfortable all-terrain vehicle, if necessary. Although the car showed itself pretty well on smooth pavement.

Chevrolet Niva as it is

Severe jeepers, as a rule, choose either the UAZ Hunter or the good old Lada 4x4, the former Niva, but those who want additional comfort and good cross-country ability, then only Niva Chevrolet shines for them for little money. Tuning this light SUV is often aimed at increasing cross-country ability, changing engine characteristics, as well as eliminating factory design flaws.

For example, Chevrolet Niva until 2010 was produced only with crosses on the drive shafts. The design is reliable and time-tested, but quite noisy and vibrating. Plus, it's heavy. After 2010, constant velocity joints were installed from the factory on the SUV. The car is quieter and more reliable. In addition to other little things, this is all that was changed at AvtoVAZ in the design of the SUV. The rest is the work of the owners.

Chevrolet Niva engine tuning

80 full-time horses is frankly not enough for a car with off-road ambitions, and 127 torque forces is just laughter for an all-terrain vehicle of this class. Therefore, first of all, you should pay attention not to the appearance, but to the power and torque. Here you can go in several ways:

replacement of the cylinder-piston group and correction of the timing - forged pistons and a lightweight camshaft with different cam angles, installation of larger diameter valves in the block head, all this will increase the filling of the cylinder with the working mixture and improve the ventilation of the combustion chamber;

finalization of the exhaust system;

installation of a lightweight flywheel;

flashing the electronic engine control unit, chip tuning, can also add a few horses.

A separate item of expenditure may be the installation of a Garrett turbocharger, adapted to the VAZ engine. The price of the kit is about 45,000 rubles, and it includes the Garrett 1752-5005s turbocharger itself, a set of fasteners and seals, a frontal intercooler for cooling the turbine, a kit fuel injectors increased performance, reinforced oil pipeline, gaskets and air ducts. It's really, good way increase the power of the Nivovsky engine up to 200 forces, depending on the degree of engine preparation.

Chassis and suspension upgrades

The cross-country ability of the Niva Chevrolet is somewhat inferior to imported classmates, and the main reason for this is the geometry of the body and the unification of the chassis and suspension with the old Niva and with other VAZ models. We won’t be able to do anything with the body, but lifting the suspension will increase not only the clearance and cross-country ability, but also make the Niva more attractive in appearance. Suspension lifting implies an increase in ground clearance by 90-110 mm.

You should not get excited here, since the drives have acceptable operating angles. It is necessary to prepare for the fact that the CV joint mileage will not change for the better in any case, since the factory working angle will be changed. The center of gravity of the car will also shift, which can cause rolls and lead to a rollover of the car, as well as a deterioration in handling in general. Maximum size tires that can be installed on a Chevrolet Niva - 235/75 with a 15-inch bore.

Installation of additional off-road equipment

The first assistant on the road is a winch. Power winches for Niva are commercially available and they can be different types, starting from a stationary device mounted in the cavity of the front bumper, ending with powerful removable winches installed on a special platform. It attaches to the front eyelets or to the front bumper mount. Most often, electric winches are installed, but there are options with a manual mechanical drive.

When overcoming a ford, there is a danger of getting an engine water hammer. Water enters the manifold, the combustion chamber, as a result of which the pistons are destroyed, the connecting rods are bent and even the cylinder block is often damaged. To prevent water hammer, use a remote air intake, snorkel. It is attached to the front body pillar, as in the photo, and it takes air at a high altitude, which prevents water from entering the engine.

Interior tuning is usually reduced to simplifying the panels, which makes it possible to carry out better cleaning, but there are also options aimed at increasing comfort. But in such a car, cross-country ability and safety are important, so many prefer to install power thresholds, fenders, additional lighting, raid trunk. Tuning Niva correctly and hospitable to all off-road!

NivaChevrolet- new modification car off-road VAZ 2121, which was produced in Soviet times. New model received a streamlined body, modern technical options, such as power steering, electric exterior mirrors, headlight range control and air conditioning. Despite this, the car remained Spartan in terms of equipment. Such a preservation of the concept laid down in the first modifications of the VAZ 2121 made it possible to attract the attention of consumers due to ease of maintenance and a relatively high degree of patency. In other words, the Niva Chevrolet is perfectly adapted to domestic light off-road conditions that prevail in most areas.

The new design and some technical options of Niva Chevrolet did not make the car the pinnacle of technological thought, but at the same time left huge opportunities for realizing external tuning Chevrolet Niva, as well as improve its practical characteristics.

Most often, off-road tuning is carried out. It's not complicated technological process, it is enough to install the following elements on the car:

Power harness. Includes a heavy duty front bumper made from bent steel tubes with winch platform. It is not difficult to make this product, you only need to have a tool and equipment for working with metal: a pipe bender, a grinder, a welding machine
Off-road tuning Chevrolet Niva necessarily provides for replacement regular disks and rubber. The following sizes are perfect here:
1. 215/75/R15.
2. 205/70/R16.
3. 205/80/R16.
The first digits are the tire size, its height and width, the designation after the letter R is the disk diameter. For the last two values, it may be necessary to refine the front wheel arches. Everything will depend on the width of the tire.
Snorkel Installation - exhaust pipe that goes to the roof. This is necessary if Niva Chevrolet will be operated in extreme off-road conditions.
A separate item is the installation of a winch on a Chevrolet Niva. Do not assume that this equipment is necessary only for those who participate in competitions. This practical equipment will be a great helper during outdoor recreation, as well as in the country and fishing. It is enough to install an electric winch and everything will be easy for the car, it will be able to pull itself out of the pit, ditch, and also help others. The body of the equipment can be hidden under a homemade metal casing.

Chevrolet Niva off-road tuning can be supplemented with protective, military paint, matte or glossy. This requires certain knowledge. The process of repainting is quite laborious and requires an appropriate mark in technical documentation, therefore, painting is not an obligatory element of tuning a 2123 Chevrolet Niva.

Chevrolet Niva engine tuning

There are a huge number of options for refining the Niva Chevrolet engine, which will significantly increase its technical characteristics:

Replacing the crankshaft and piston rings gives an increase in volume of 0.1 liters
Nozzle replacement
Replacing the control unit
Correction of the engine geometry by increasing the diameter of the valves and the pusher well for the intake and exhaust channels. New tappets with a diameter of at least 1 mm are required
Sealed valves increase power by 10%
Replacing the catalyst with a flame arrester. This is tuning exhaust system Niva Chevrolet, but it helps to improve technical indicators engine

All these operations require direct intervention in technical device car. Chip tuning of the Chevrolet Niva engine is optimal - this is work with the brains of the engine - the injector. This requires software knowledge. With its help, the technical parameters of the machine are changed. This method is the least expensive.

DIY chip tuning Chevrolet Niva video.

Chip tuning Chevrolet Niva involves the use of a special connector for connecting to a car and a laptop. The software is very important here. It is desirable that it be licensed. But this option is quite expensive. You can download good assemblies on the Internet, but first you should read reviews about them. Re-flashing, chipping the engine on average takes up to 1 hour. At the same time, the torque and power increase by an average of 10%, the stroke becomes smoother, and the motor runs quietly and gently. At the same time, fuel consumption remains at the same level or decreases to an average of 1 liter per 100 km.

Useful advice

Chip tuning is carried out only when the car is fully functional. Otherwise, serious technical problems may arise. For example, fuel consumption will become uncontrollable.

Chevrolet Niva suspension tuning

Niva Chevrolet was created for cross-country driving, so the car's suspension is able to withstand serious loads, but not all and not always. Therefore, to improve patency, it is necessary to strengthen the suspension.

The most popular and relatively simple is do-it-yourself Chevrolet Niva lifting, that is, an increase ground clearance. For this, special kits are sold, the installation of which will require the use of metalwork and pneumatic tools, as well as the presence of a lift. Actually suspension tuning consists of the following steps:

Strengthening the suspension with shock absorbers, they are installed in parallel with the regular ones. First you need to prepare fasteners for them.
Refinement in terms of the reliability of standard fastenings of support units
Installation of suspension struts or gas-oil shock absorbers
Replacing standard springs with reinforced modifications
Installation of non-adjustable steering knuckles
Replacement of standard hubs with rotary ones
Particular attention needs to be paid jet thrust, they need to be strengthened.

Interior tuning Chevrolet Niva

Do-it-yourself tuning of the Chevrolet Niva interior is traditionally its hauling. Genuine leather on the seats or its high-quality substitute will become a special chic. Chrome or mahogany imitation inserts may appear on the doors.

A good, relatively simple, but expensive replacement for sports seats will be. An essential attribute is the new wheel. If you need to save money, it is best to use a technique called flocking - applying cotton dust to the skin, which creates a hairy effect. The new interior can be given any color.

You can also replace regular seat belts, install xenon or bi-xenon interior lighting, bottom. Additional soundproofing will not interfere. Instead of a standard stereo system, an on-board computer will look great - it is also a functional solution.

Chevrolet Niva panel tuning

Here the expression will be relevant - the need for inventions is cunning. Chevrolet Niva torpedo tuning will help you realize your own fantasy and available materials:

Construction foam
Various homemade elements
Epoxy - epoxy resin
grinding tool

All of the above will give the standard torpedo a new stylish look.

The second improvement option is to fit a torpedo from other car models. This may require alteration of standard mounts. But the same can be done on the new torpedo, which will be a rational solution. A good option would be to upholster the torpedo with some expensive material, such as leather.

Cars of the Volga plant are not considered prestigious. Even the updated Niva, which Chevrolet specialists had a hand in creating, often causes criticism in terms of comfort level, engine power and other parameters.

Many motorists want to improve their car with their own hands, and often this desire is associated not only with improving its performance, but also with the desire to adjust the car to their ideas about a good car, to give it individuality.

Most owners are limited external changes: do-it-yourself installation of aerodynamic and purely decorative body kits, replacement rims, etc. The real tuning starts with the engine. Chevrolet Niva tuning masters have extensive experience in refining standard Niva engines.

In their arsenal, the replacement of factory pistons and crankshafts, which allows to increase the working volume of the engine, alteration of the valve system, changing the valve timing, reducing the gas-dynamic resistance of the exhaust and intake systems, installing a lightweight flywheel and other measures. All this allows you to significantly increase engine power and improve the acceleration dynamics of the car.

Tuning an engine is about improving its performance, not complete replacement, as Australian hot rod lovers did, “shove” a five-liter monster that somehow got into their “Niva” under the hood.

Chevrolet Niva engine tuning parts

The increase in engine power and thrust is carried out in two directions: an increase in the working volume and an increase in the efficiency of gas dynamics.

The first way is to bore the cylinders and replace the standard pistons with larger diameter pistons. Thus, it is possible to increase the working volume from the standard 1700 to 1900 cc. In addition, it is possible to install a crankshaft with an increased shoulder and replace the connecting rods with shorter ones, which increases the piston stroke.

New pistons can be cast or forged. Forging produces particularly durable parts with an increased resource, but the main thing when tuning is perfect balance and accuracy. The mass balance of the piston and the forces acting on it, the dynamic balance of pistons, connecting rods and crankshaft - all this the necessary conditions to reduce vibrations, minimize stress on all parts and increase their service life.

An increase in the working volume entails the need to improve the scavenging of the cylinders. This is the only way to fully realize their new potential. To ensure greater gas exchange in the cylinder, valve seats are bored and valves of increased diameter are installed. The same effect can be achieved in a simpler way - by replacing the standard valves with T-shaped ones, which have a thinner profile and open a passage of a larger cross section for the flow of gases.

Turned valves have less weight and are able to work without "hanging" for more high revs. Pushing the moment of breaking the timing kinematics into the high-speed zone allows you to shift the operating frequency range up to 8000 rpm and get a noticeable increase in power due to this. In accordance with the general logic of reducing the inertia of moving parts, in order to achieve the maximum effect, the upper plates of the valve springs, the springs themselves, and the pushers are replaced.

For efficient operation of the engine at high speeds, other valve timing phases are needed, taking into account the high piston speed and the inertia of gas processes. More than a hundred tuning camshafts with modified cam geometry have been developed for the Niva engine. Among them, you can choose a shaft that provides the desired amplitude and the required moments of opening and closing the valves.

To fine-tune the valve timing (FGR), a split gear with a movable crown is installed on the camshaft. When assembling a timing kit, you need to take into account the existing software systems for flashing the engine control unit.

Refinement of the Chevy Niva engine with your own hands on the video:

Chip tuning engine Chevrolet Niva

The standard parameters of the engine management program are designed for economical driving and the widest possible range of modes, which “smoothes out” the potential capabilities of the motor. By changing the program, you can achieve a significant increase in power from it.

It is quite obvious that the control of the converted engine, which has an increased working volume and modified FGR, should differ from the standard one.

There is a prejudice among chip tuning masters that it is better not to interfere in the operation of the Niva engine computer. Thanks to the self-learning ability inherent in it, it independently optimizes the operation of the motor. This is indeed true for Bosch 7.9.0, M7.9.7 and M7.9.7+ ECUs.

Designed for tuned engines electronic blocks control can be reflashed and thus bring the control parameters in line with the new qualities of the motor. Chip tuning "Chevy Niva" can give up to 15% increase in power. Having made significant efforts to refine the engine, it is hardly worth neglecting this possibility.

Chevrolet Niva transmission tuning

In the tuning of the Chevrolet Niva transmission, the most popular event is the fight against vibrations, the source of which is the front gearbox. Often they try to install a self-locking gearbox. If vibration reduction is in any case useful, then limited-slip differentials, ball or hypoid limited-slip differentials do not fit very well with the Niva and can lead to complications.

Given the off-road nature of the Niva, many owners prefer to increase its cross-country ability by installing onboard (wheel) gearboxes. With these gearboxes, the car becomes much higher, the torque on the wheels increases, it becomes possible to install larger diameter tires or even tires on the car. low pressure that allow you to overcome wetlands and deep snow.

Chevrolet Niva suspension tuning

The simplest but most useful modification of the suspension is the installation of polyurethane elastic elements: silent blocks, bushings, limiters, etc. The increased resistance of these parts to loads, low and high temperatures, oil products are very useful for a car designed for bad roads.

Shock absorbers have a big impact on the driving performance of a car. Fans of speed are better to put shock absorbers with increased stiffness. This will improve the stability and handling of the machine. For those who often drive on bad roads or with a heavy load, it is better to prefer gas or gas-oil shock absorbers. And for fans of cross-country rodeos, there is the opportunity to put dual shock absorbers. Such refinement will help to cope with the car in conditions unthinkable for the average driver.

Off-road SUV tuning

Improving off-road qualities is perhaps the main direction of Niva tuning. For all its merits, the serial Niva is still road car increased permeability. The possibilities of lifting the car have already been mentioned above. Now it is worth mentioning the possibility of overcoming the fords.

Hydraulic preparation of the machine includes the installation of a snorkel, protection of breathers and electrical wiring. When installing a snorkel, it is important to correctly calculate its cross section. The dynamic air resistance in it is the greater, the greater its length and the stronger its cross section differs from a circle. If the air duct is too narrow, the filling of the cylinders may deteriorate, which will lead to a decrease in engine power.

The breathers are protected by rubber hoses brought to the highest point. engine compartment and equipped with filters.

Example off-road tuning Chevrolet Niva on video:

Tuning is endless, as are endless possibilities for improvement. Each car owner has their own preferences, and tuning provides the means to bring the car to an individual ideal. Before you start implementing your ideas, we advise you to use virtual programs, with which you can try on various modifications for your car on a computer.

Under the article, we have collected several photos with the most interesting tuning options for the Chevrolet Niva, which, perhaps, will give you an idea for improving your car.

Chevrolet Niva is the so-called workhorse, which is unlikely to fit for exhibitions or rampant races, so the goal of tuning is to transform appearance, increasing practicality, finalizing technical parameters, improving the comfort of the driver and passengers, as well as increasing cross-country ability in off-road conditions. The amount of work directly depends on your skills, wallet thickness and desire. Skills, by the way, are very easy to improve. Chevrolet Niva tuning can be performed in three key options - improving technical parameters, visual modernization and a combined approach. What options are the most affordable and effective?

External transformation

Visual tuning Chevy Niva is the most successful way to quickly achieve the effect. A cardinal approach is a change of color, but it will take a lot of time, and the price of the issue will bite many. Alternatively, use film. Professional pasting allows you to extend the life of the body by protecting it from chips and scratches. Of course, outwardly, it will be a real reincarnation.

You may also be interested in our expert's article on features and nuances.

When choosing a film, look for options with microchannels, thanks to which you can process curved surfaces. Avoid Chinese manufacturers, since the quality of such products is enough for a maximum of interior decor.

It is worth paying attention to the following manufacturers.

3M is a Japanese brand that offers a film with the effects of unpolished steel, brushed metal or carbon look.
Hexis is a French product, among the range of which pearl effect film deserves the most attention. Imitation of metal, plastic or leather is also available.
Orafol – German manufacturer, whose activities are focused on the production of premium films. A wide range of colors and textures are presented.

Work order

If this is the first time you bought a film and do not know if you can stick it, practice on a small flat area without bends. The level of dust content in the room should be kept to a minimum. Do not save on consumables and be sure to purchase a primer. We are talking about a special adhesive composition, thanks to which to cope with sharp corners Much easier when pasting.

The stages of work are as follows.

Clear the selected element and mirror the pattern.
Choosing the area between the middle and edge of the part as the start zone is based on the configuration.
Take your time when fixing the vinyl, take the trouble to get rid of all the bubbles with a soft spatula.
Use a primer to further fix the film around the edge.
Remember that the use of a building hair dryer allows you to make the material more elastic and it will take the shape of the desired surface. It is very easy to overheat the film on a surface with an uneven structure, be careful.
Excessive material tension can cost you spectacular relief.

Salon modernization

If you have already achieved the external transformation of the car, also do the tuning of the Chevrolet Niva interior with your own hands, otherwise the contrast between the exterior and the faded interior will be too obvious. Options for internal improvements can be as follows.

Buying a new steering wheel or leather upholstery. Visual superiority will be in harmony with practicality.
Installation of a DVR, audio system, navigator and other modern electronics. An alternative is a complex multi-system, including all the mentioned functions.
Change dashboard and torpedoes.
Inserts on regulators, gear knobs and transfer cases can be tinted, decorated with stickers or completely replaced.
If you are not satisfied with the chairs, feel free to change them, but you can also get by with new covers or upholstery replacement.
Noise isolation, despite its cardinality, will not change the appearance of the car in any way, but comfort will increase many times over.
Small tuning in the form of pedals, stickers or LEDs allows you to make point accents in different areas of the cabin.

Trunk tuning

Having transformed the appearance and interior, you can make tuning the Chevrolet Niva trunk, because it should not differ too much from the interior. The functions of this part of the SUV are not limited to luggage storage. Here you can find a place for a powerful speaker system, which can be supplemented by LEDs on the lid and around the perimeter. rear arch doors. 320-liter volume allows you to install here even an ergonomic billiard table with automatic system unfolding and extension.

Optics

The optics deserve special attention, and you can transform the headlights thanks to a special glow. Get GT Block Small reflectors and Hiper Flux yellow LED chips. Additionally, you will need black paint in the form of a spray.

The procedure will be as follows:

Remove the headlight and use paint to treat the substrate.
Create 16 reflector holes at the bottom of the case. Make sure that the distance between them is strictly the same. It will running lights daylight, so the LEDs must be white. After connecting the elements into the circuit, it remains to connect them to the standard power supply.
The yellow LEDs are just right for the turn signal repeater. Use thin plastic as a base, in which you need to make 4-6 vertical and 10 horizontal holes. They must be symmetrical. Use the wires to connect them and also connect the standard wiring.
It remains to collect the headlight and return it to its rightful place.

You can use other options for localizing holes - it all depends on your imagination. You can replace individual diodes with an LED strip, so you save time and effort.

Do-it-yourself Chevrolet Niva tuning will save on energy consumption, extend the life of lighting elements and increase brightness.

Engine

To transform the VAZ 2123 engine, you will have to delve deeper into the topic of tuning. If elementary concepts about the device are unknown to you, it is better to refuse your own manipulations. Realize that you, as the owner, will have to get into the design of the engine, change specific elements and perform other operations, errors in which can be fatal. So, if you are confident, go for it.

Install new piston rings and crankshaft. So you can increase the volume of the motor by 100 ml. Despite the meager change at first glance, the technical parameters will actually improve significantly.
You can expand the possibility of chip tuning by installing a new control unit.
Replace nozzles. Prioritize efficiency and quality if you want to achieve fuel consumption that is good for both performance and power.
You can also work on the geometry of the engine. An increase in the diameter of the wells and valves of the inlet and outlet channels will help you in this matter.
You can replace the traditional catalyst with a flame arrester, which will significantly change the dynamics of the car and the operation of the exhaust system.

Since such manipulations, again, require experience and knowledge from the driver, drivers often prefer chip tuning.

ECUs are present on each modification of this model, they are responsible for controlling all engine systems. If the standard factory firmware upsets you, perform a Chevrolet Niva chip tuning, you can do this with the control unit removed or directly on the car. In the first case, take care of an additional power supply with a suitable connector, as well as a matching data input unit.

Diagnostic mode. When connecting a laptop to the computer, you can identify problem nodes electronic system and troubleshoot the oxygen sensor and catalyst. Installing the firmware is only allowed on the full serviceable equipment. Among the advantages of the upgraded firmware is not only the speed of work (2 hours maximum), but also:

reduction of fuel consumption to a liter for every 100 km;
increasing the dynamic performance of the engine;
power increase by 10%;
stabilization of the engine in all gears;
minimum financial costs.
