As the name suggests, the VAZ 2107 air filter (injector) is designed to clean the air supplied to the combustion chamber from dust. A clogged filter creates additional resistance to passing air. As a result, the composition of the air-fuel mixture changes, fuel consumption increases and engine power decreases. If the filter is damaged, it will allow dust particles and grains of sand to pass through, which, when entering the engine, will begin to act as an abrasive, increasing wear on the rings and cylinder surface. Therefore, the filter must have the proper density, which will not allow dust to enter the engine, but will not create unnecessary resistance to air flow.
How to change the air filter on a VAZ 2107 with your own hands?
Replacing the air filter on a carburetor car is very easy. The need for the part is explained by the fact that it cleans the air that enters the combustion chamber of the engine. Without proper filtration, it will be difficult for air to enter the system, which will lead to a number of malfunctions. Therefore, the filter must always be in good condition.
Replacement frequency
The technical maintenance schedule for the VAZ 2107 engine air filter provides for replacement every 30 thousand kilometers. An important role is played by the conditions in which the air filter operated and, based on this, it needs to be changed more often or less often.
There are no strictly strict service lifespans, and only the condition of the previous filter element will determine how often to change the part.
In classic car models there are no on-board computers that would measure fuel consumption, and therefore, based solely on your memory, it is necessary to make replacements.
Signs that replacement is needed:
Why change
But really, why? If you buy a filter, let it sit until the end of the car's service life. But no, you can’t do this under any circumstances, otherwise the car will really last very little.
Clogged air filter
There are several reasons why the air purifier should be replaced on a VAZ 2110.
- Pollution. As you use it, the element becomes dirty. The formation of contaminants leads to increased fuel consumption and difficulty starting the engine.
- Lack of proper air draft in the cabin, which makes it very stuffy inside. In parallel with this, the engine may operate unstably and floating speeds may appear. All this suggests that it is time for a replacement.
- Comprehensive service. When buying a car second-hand or during scheduled maintenance, the new owner, as a rule, immediately changes all consumables, fills in new oil, and installs new filters.
Replacing the air filter on a VAZ 2107 injector
Replacing the air filter on a VAZ 2107 injector is not done as often as on a conventional carburetor engine. This does not exclude the fact that its serviceability and condition should not be monitored and changed in a timely manner.
And due to the frequent entry of dust into the DMVR, the functions of the filter element are lost and it wears out many times faster, which leads to premature replacement. On fuel-injected cars, the location of the air filter is under the air duct. And before replacing the old one with a new one, unscrew the air vent cap, lift it up and remove the old filter from its seat. Before positioning the new part, the air housing is wiped, and then installation is carried out.
Preparation
You don't need a whole set of tools when working with filters. You can get by with one 10mm wrench and a clean napkin or rag. You can change the air filter yourself in 10-15 minutes.
Filter models considered suitable for an injection engine are MANN C2443/1, LADA 21120-1109080-82. For a carburetor engine the filter element is round, and for the injector it is square.
Inexpensive domestic filters cost about 80 rubles. German SCT air filters are suitable for carburetor engines of VAZ 2101-2107, 2108-21099 cars and cost about one hundred rubles.
The choice of filter can also be made based on its type:
How to remove and install correctly?
The process of replacing an old filter with a new one is carried out in two stages:
Step-by-step instructions for installing a new air filter:
Causes of device malfunction
Signs of a device malfunction include incorrect readings and noise during operation.
The reasons may be the following:
- the counter is faulty;
- the fastening nuts are loose;
- break of a flexible cable;
- the tip or the socket into which it is inserted is damaged;
- the drive is broken or the socket through which it connects to the gearbox is damaged;
- The cable sheath is damaged.
Checking the mechanism for functionality
To diagnose the cause of the meter malfunction, you need to lift the car using a jack and remove the meter cable. At the next stage you will need an assistant. One person rotates the raised wheel while a second person watches the flexible shaft. If the cable rotates, then the reason is in the counter; if rotation does not occur, the cable will have to be changed.
Consequences of untimely replacement
If you do not change the filter in time, repairs cannot be avoided. A contaminated part negatively affects engine performance, since air must constantly pass through the element to get into the fuel tank and system. This may result in low engine power.
The filter element has quite a large resistance, but if it is absent altogether, the consequences for the machine will be terrifying.
A dirty and clogged filter not only does not perform its direct functions, but also entails a number of negative aspects:
Therefore, the problem of replacing the filter element on a VAZ should be approached seriously in order to avoid serious damage in the future.
Replacing the air filter of VAZ 2105, 2107, 2108 on carburetor and injection engines is simple, quick and without much outside help. The main thing is to replace it in a timely manner and monitor the quality of the selected filters.

Article number and cost of the original VAZ 2107 air filter
The original air filter for the carburetor VAZ 2107 has article number 2101-1109100. Its price is 80-200 rubles.
A completely different air filter is installed on the injector. Consumables are not interchangeable. The article number of the filter element for the injection VAZ 2107 is 2112-1109080. The cost of such a consumable ranges from 200 to 340 rubles.
Third-party manufacturers also produce filter elements for the VAZ 2107. Among their products, there are many decent options at an attractive price. The tables below present the best analogues, which are recommended to be taken instead of native filters.
Air filter for VAZ 2107
From the name “air filter” it becomes clear that the device is intended for air purification.
On VAZ 2107 cars, the air filter is a mandatory device that cleans the air supplied to the engine combustion chamber.
If it becomes clogged, the debris will prevent air from flowing into the engine, so it is very important that the part in question in the car has always been in good condition.
What is an air filter
An air filter is a device that filters the air entering the fuel system. All modern cars are equipped with air filters, including the Lada family with carburetor and injection systems.
The main purpose of the air filter is to clean the incoming air from sand, dust, soot, midges, small particles, plant seeds and other substances. The absence of the product in question will lead to the fact that all of the above-mentioned substances will enter directly into the fuel system, and after a short time it will simply be clogged.
It is important to know! All types of cars, including the VAZ 2107, must have an air filter, and it is necessary to monitor its condition and, if necessary, replace it in a timely manner.
A clogged element negatively affects engine performance, since air must pass through the device to enter the fuel system. This reduces engine power accordingly. The resistance of the product in question is quite high, but in its absence the consequences for the car will be simply catastrophic.
In a car of the classic VAZ 2107 family, the design of filters for the injection and carburetor injection systems is different.
For the injector, the product in question has a rectangular shape, and on carburetor engines round-shaped filters are installed. Both types of products consist of a plastic housing and a filter element.
This element is presented in the form of paper, which contains micro-pores and traps all types of small particles.
The filter element is located in the lower left corner of the photo
Since the creation of the part in question, many varieties have appeared. Types of air filters are divided into the following options:
How to replace the timing chain on a VAZ 2107
How often to change the air filter on a car
Replacing the part in question depends on the condition of the filter element. The condition of this element is influenced by factors such as the terrain in which the vehicle is operated, the frequency of operation of the vehicle, and the seasons.
The VAZ-2107 injector air filter needs to be replaced somewhat less frequently than on carburetor models. In some manuals you can find a figure of 30 thousand kilometers - this is the recommended mileage for replacing the part in question.
In reality, this figure does not mean anything, since the main condition for replacement is clogging of the filter element.
The part in question cannot be repaired, but if the filter elements are in good condition, that is, there is no damage and its color has not changed much.
It is necessary to change the air filter because when it is clogged, fuel consumption increases.
If the injection “sevens” have an on-board computer that displays an increase in consumption, then on the classics you have to rely on your memory.
How to replace it yourself
Let's look at how to replace the air filter on a VAZ-2107 car with a fuel injection system. The replacement procedure is as follows:
In conclusion, it is worth noting that the cost of the product in question is low enough to risk clogging the fuel system. A regular paper filter costs about 150-200 rubles, so be sure to check this product periodically and replace it in a timely manner.
In order to change the air filter on a carburetor seven, you need to perform similar actions, which you can learn about from the video below.
Engine crankcase ventilation system with carburetor 2105, 2107 Ozone
Purpose of the crankcase ventilation system for VAZ 2105, 2107 cars
The engine crankcase ventilation system is designed to forcibly remove crankcase gases generated as a result of engine operation. Many car owners often do not pay special attention to the crankcase ventilation system of the car engine. But in vain. It is very necessary for its normal, uninterrupted functioning.
Crankcase ventilation system design
The crankcase ventilation system for engines with carburetors 2105, 2107 “Ozone” and their modifications consists of a large and small branch. Through the large and small branches, gases are removed at high loads, through the air filter housing and carburetor; at low loads, removal occurs through the small branch, into the carburetor, and then into the throttle space.
Diagram of the crankcase ventilation system of a car engine
Engine crankcase ventilation system for VAZ 2105, 2107 cars
Operating principle of the crankcase ventilation system
Under the influence of the vacuum that occurs in the air filter housing when the throttle valves are open and at high engine speeds, crankcase gases are sucked out of the engine crankcase and forced through the breather and ventilation hose into the air filter cavity after the filter element. This operates a large branch of the ventilation system. In this case, additional removal occurs through the small branch. The spool, which is part of the small ventilation branch, located on the axis of the throttle valve of the first chamber, inside the carburetor body, increases the passage opening for the passage of crankcase gases as the throttle valve opens and its axis rotates.
When the engine is idling or with light loads, the throttle valves are either closed or slightly open, the vacuum in the air filter housing is too low and ventilation through the large branch is sluggish, and under closed throttle valves the vacuum is quite high. Therefore, ventilation occurs through the small branch of the crankcase ventilation. The spool covers the gas exhaust hole and they pass only through a small calibrated hole, thus preventing unstable engine idling due to excessive “suction” of foreign air into the carburetor.
Scheme of operation of the spool device of carburetors 2105, 2107 Ozone
Checking the crankcase ventilation system
It is impossible to test a large branch of the ventilation system. It is necessary to visually assess the oiliness of the engine - oil leakage from under the oil filler cap, valve cover gasket, crankcase ventilation hoses, crankshaft seals, condition of the spark plugs. In addition, remove the cover of the air filter housing and inspect the housing cavity and the filter element for oiling.
Of course, all of the above may be a manifestation of other malfunctions (wear of piston rings, loose connections, wear of oil seals, failure of spark plugs), but first, before searching for other faults, it is worthwhile to inspect the crankcase ventilation system, since there is nothing particularly complicated about it, and it’s better to start repairs from the simplest.
We check the small branch of the ventilation system. We put the tube on the hose fitting of the small ventilation branch and blow through it with our mouth. Air should flow fairly freely; if it doesn’t, the system’s channels are clogged and need to be cleaned.
We try to blow again and at the same time rotate the throttle axis of the first chamber by the lever. As the axle turns, the air should flow easier and easier, since the plastic valve located on the axle opens the hole for air passage more and more.
Again, if such purging is difficult, then it is necessary to clean the channels or spool on the axis in the carburetor.

Repair
Repair of the ventilation system consists of cleaning, rinsing and blowing out its components. If this is not done on time (and as the engine wears out, the system becomes more and more clogged), then expect oil in the air filter cavity and oily spark plugs. As a result, the engine begins to operate intermittently, stalls, starts poorly, the carburetor ceases to be adjustable, its jets and channels become contaminated with deposits. The pressure in the crankcase increases and oil begins to ooze from under the seals, gaskets, and oil filler cap. This is the unsightly picture that emerges from a system that few people pay attention to.
Some rush to “overhaul” the engine, blaming worn-out rings, and the reason for the deterioration of its performance is simply some piece of sediment stuck in one of the ventilation tubes.
1. Remove the hoses of the large and small branches of the crankcase ventilation. We wash them with acetone or gasoline, then blow them with compressed air. If there are a lot of deposits and they have hardened, we perform washing and blowing several times.
2. We disassemble the engine breather. We take out the tube through which gases are sucked out of the crankcase, and remove the oil separator. We wash everything, wipe it and put it back in the order in which it was removed. If all deposits cannot be removed at once, then soak the removed parts in acetone or gasoline for an hour.
3. Remove the air filter housing. We clean the ventilation system channels in it through the fittings on which the large and small hoses are put on. Blow with compressed air.
4. Remove the carburetor from the engine. Disconnect its lower part. We take out the throttle valve axis of the first chamber. We wash the channels and openings of the ventilation system, the spool. Blow with compressed air. Let's put everything back together. If you forgot how, look at the images.

Removing the air filter housing VAZ 2107
The VAZ 2107 air filter housing is removed to replace it in case of various mechanical damages, as a result of which the integrity of its housing has been compromised. To remove, you will need a standard set of tools, namely pliers and a set of screwdrivers. Once you have everything you need, you can begin work.
To dismantle the filter housing, you must perform the following sequence of actions:
At this point, work on removing the VAZ 2107 air filter housing is completed. Before installing the filter housing back into place, you must remove all rubber supports.
The supports must be installed in the holes of the housing mounting bracket, and the housing itself must be simply placed on them during installation, this will be much more convenient.
VAZ 2107 and VAZ 2106: differences between replacing the oil filter
Some car owners are wondering about the differences between replacing the oil filter on a VAZ 2106 and 2107
Experts pay attention to the similarity of the assemblies of these models and the general algorithm of actions when working
There are no significant nuances that should be paid attention to. On a VAZ 2106, replacing the oil filter is carried out according to the same procedure; the procedure is the same for most other cars
The main aspect in which there may be differences is the location of components and part numbers of components. There are also no significant differences in the location of the drain plug and oil filter; even a novice car owner can find them.
The part numbers are also largely identical, making them interchangeable. However, it is recommended to check the technical documentation for the manufacturer’s own recommendations before purchasing.
Modification of the air filter VAZ 2101-2107
One of the options for improving the power of a VAZ 2101-2107 car is to modify the air filter. Of course, this will not lead to a sharp increase in speed, but it will still have some effect. There are two ways to do this.
Cutting the air filter housing.
The air filter on the classic has a “donut” shape and is installed in a plastic casing, and air is supplied to it through a round pipe. Thus, the entire surface of the filter element is not used, which hinders the operation of the engine. You can proceed as follows.
The side walls of the air filter housing must be cut clean. Leaving them in only four places, where the latches are located that tighten the top cover. The exhaust gas pipe can simply be secured below, under the engine - they do not pose any danger in terms of fire. In addition, in this way the engine will not “inhale” non-flammable gases.
Such filters are quite expensive, but have a very long service life; it is enough to simply wash them periodically (every 10-15 thousand km) with a special liquid. Zero resistance filters are universal and differ only in the shape and diameter of the outlet hole.
Such a filter is installed at the inlet of the air filter housing and is extended by a pipe secured with clamps. The old filter is simply removed.
The only negative side of this solution is that crankcase gases will flow through the exhaust gas pipe, bypassing the air filter, although nothing bad will happen in this case.
The advantage of installing a zero-resistance filter compared to cutting off the casing is that when the first cold weather sets in, you won’t have to look under the hood again.
There are other “folk” ways to modify the air filter, but they are either ineffective or lead to problems with engine operation, increased wear and even breakdowns. Therefore, we present only the two above-described methods for modifying the VAZ 2101-2107 air filter, which are safe and can actually improve driving comfort.

Engine power system on a carburetor VAZ 2107
The power supply system of a carburetor engine is the entire path of fuel, from the tank to the spraying of the mixture through the intake manifold into the cylinders of the VAZ 2107. It is the totality of all the processes that ensure this long path that supplies the car, as a result of internal combustion, with the energy that humanity has learned to use.
What main parts does the VAZ 2107 power system include?
- The carburetor is the final and most important device of the system, mixing fuel with air in the required proportions;
- Corrugation, or a device for taking in warm air, is an indispensable tool for driving in the cold season;
- Air filter intake;
- Control cover for air access to the filter;
- The air filter cover, or “air”;
- The actual air filter VAZ 2107;
- Filter housing, which is mounted on top of the carburetor;
- Float sensor for gasoline level indicator in the tank;
- Gas tank filler neck;
- Hose for ventilation;
- Gas tank housing;
- Fuel piping system;
- Fuel hose system;
- Fine fuel filter;
- Fuel pump VAZ 2107.
As can be seen from the diagram, all of the listed components can be conditionally divided into two large groups: air supply devices and fuel supply devices for mixing in the carburetor.
In addition, on the dashboard of the VAZ 2107 there is a control device showing the fuel level in the tank with a control light, which approximately begins to “blink” when there is fuel remaining at 80-100 km, and lights up with a steady light when there is about 4-5 liters left.
During winter operation of the VAZ 2107, after a long period of parking and condensation freezing in the gas tank, the needle may completely oscillate until the ice disappears.
In addition, in the fuel supply system there are supply lines - first a system of fuel lines, then hoses. The force that causes gasoline to flow out of the gas tank is the negative pressure created by the VAZ 2107 fuel pump.
We will describe some maintenance issues and simple repairs of the fuel supply system that arise when operating a VAZ 2107 car.
Air supply system. Control cover and thermostat positions.
There is a special marking on the cover and a lever. If it is turned and fixed in the hot position, then warm air is taken from the corrugation, this is done in winter. If the lever is turned to the opposite cold position, unheated air is taken in.
Such a simple device, however, causes misunderstandings. For example, some car enthusiasts understand everything exactly the opposite. Hot means to use in the hot season, and cold means winter. Be careful! If you mix it up, the carburetor will work with increased load in winter, the engine warm-up time will increase, and more frequent carburetor repairs may be necessary.
Cabin filter for VAZ classic
Good afternoon. Today we will tell you how you can install a cabin filter on any VAZ classic.
about the advantages of having a cabin filter ; anyone who has ever disassembled the stove has seen how many yellowed leaves and other debris can be found on it, which greatly impedes the passage of air through the radiator, as a result of which the stove does not heat well, etc.
Well, there’s also no need to say much about the dust on the dashboard and throughout the cabin - a classic stove is like a vacuum cleaner - it sucks in everything from the street without filtering, which leads to the need for almost daily cleaning. Well, we breathe this muck in the cabin, and if you also have children, then it’s harmful to them on the square.
In general, the modification is definitely useful, uncomplicated, and we will show you it using the example of a VAZ-2107; with minor adjustments it can be applied to any classic. First of all, we get rid of what we think is an absolutely unnecessary part on a classic stove - the cover for regulating the air flow from the street.
After all, when it is closed, even when the stove is on, the air intake is minimal, and there is no other way for the stove to take air based on the recirculation principle, so for everyone it is almost always in the open position. Here we are talking about this “cover”:
Next we need a cabin filter from the Chevrolet Niva. Its standard dimensions are 15 by 25 cm. In terms of width for the classics, 15 cm is a lot, you need about 12-12.5 cm. To do this, use an ordinary stationery knife to cut the filter across the accordion, departing 3 - 2.5 cm from the edge.
Along the edges of the filter there are strips of foam rubber, they create a seal, strips of foam rubber are also laid on the left and right, they keep the filter from moving left and right and additionally seal. Our filter is installed and ready to perform its normal functions.
Since we are making this modification using the example of the VAZ-2107, we also installed “filters” on the central deflectors made of spandbon; over the course of several months, they also accumulated quite a lot of dust and debris:
We assemble the stove, enjoy the clean interior, get used to the absence of dust in the cabin, dirt and leaves on the radiator, in general, to all the delights of the more modern VAZ brothers, which the classic was deprived of. We will be glad to see you on our forum at the VAZ classic club . There we will answer any questions you may have about your car. Good luck to everyone on the roads!
