The need to replace parts in the design of a car is a completely normal phenomenon, especially when it comes to consumables. The Russian station wagon called "Lada Largus" is no exception to the general rule, so owners often have to change certain nodes in its design.

Most often, unscheduled repairs are provoked by contamination of the car filters. In road conditions in Russia, the air filter gets dirty faster than others. That is why our resource decided to cover in detail the question of how to quickly and without any problems replace the Largus air filter.

Purpose, design and service life

The air filter of any car, including Lada Largus, is very important for its normal functioning. This is due to the fact that this unit filters all the air entering the cylinders along with gasoline. In the event that the air-fuel mixture systematically has foreign impurities during the operation of the machine, then the motor resource will be reduced several times. Given this fact, we can state: the air filter in the Lada Largus-Cross and the regular version of the model must be kept in good condition, constantly checked and, if necessary, replaced.

The design of the node is not something complicated. It consists of three main elements:

• boxconnecting the filter element with all airways and protecting the internal parts of the assembly from adverse external influences;
• filter element, made like an accordion and purifying the air from impurities;
• seals located along the edges of the box and preventing foreign fractions from entering the assembly.

Air filter pollution, or rather, its filter element, on Lada Largus is an inevitable process. A similar phenomenon is due to the fact that there is no ideally clean air in the atmosphere, therefore dust, water and other fractions, which are undesirable to enter the engine, often get stuck and deposited in the filter. The air filter must be replaced when engine instability occurs or when the vehicle manufacturer recommends this procedure.

As for the Lada Largus, AvtoVAZ has outlined the following periods for a scheduled inspection and replacement of the air filter on this model:

• it is important to carry out the first inspection of the node after 7,000 kilometers, and its replacement - 15,000 kilometers;
• in the future, the check is carried out every 10,000 kilometers, and the replacement is 30,000 kilometers.

Important! Filter contamination earlier than specified by the manufacturer is a significant reason to replace it. Otherwise, problems with the car engine in the future cannot be avoided.

Symptoms of a "dirty" filter

A dirty air filter on a Lada Largus will definitely not “keep silent” about itself. This problem of the car assembly, like any other, will make itself felt with certain symptoms. You should not ignore it, since operating a car with a dirty air filter really kills the engine.

The main signs that the Largus air filter can no longer perform its functions to the proper extent are represented by the following list:

• a decrease in power and agility in the movement of the car (the “dirtier” the filter, the more pronounced the problem);
• increase in fuel consumption;
• hard start of the "cold engine";
• increased engine knock.

As noted earlier, Don't delay replacing a dirty air filter.. Despite this, it is possible to use a car with such a node, but for an extremely short period - no more than 30-50 kilometers.

Important! To finally make sure that the air filter on the Lada Largus is dirty, its removal and detailed inspection will help.

Replacement

Having identified the need to replace the air filter, it is desirable to carry out it immediately. It is worth noting that this type of repair is not something complicated, so any motorist can do it. An event of this kind does not require special preparation, with the exception of the acquisition of a new filter element. Do not forget that when buying a new part, it is important to consider which motor is installed in your Largus:

• 8-valve unit uses filter part number "165469466";
• for 16-valve - "8200431051".

Replacing the Lada Largus air filter is a fairly similar process for both engine options. The template algorithm for its implementation is as follows:

Important! After replacing the filter, it is advisable to start the engine and let it run for a few minutes.

In general, the design, principle of operation and replacement of the Lada Largus air filter are not so complicated. We hope that the material presented was useful to you. Good luck on the roads!

Having appeared on the domestic market about 3 years ago, the Lada Largus model immediately began to attract increased interest from practical owners to its person. For this car, the manufacturer has provided two options for equipping power units: 1.6-liter with eight and 16 valves.

The air path filter supplied from the factory has its own code - "8200431051". In some versions of Lada Largus, the standard equipment provides for the presence of an element from Renault, which has a different code - "8201153808".

Replacing the air filter in the air supply circuit is not difficult, so the vast majority of owners easily cope with this task. Before purchasing a new filter, it is recommended to first remove the old component and measure its geometric parameters.

General Aspects: When to Change

The instruction that is attached to the Lada Largus assumes the need to replace the filter every 20 thousand kilometers. Here we recommend making an adjustment for this scheduled maintenance period and reducing the designated period. This need is caused by the peculiarities of operating a car in an environment of increased pollution and gas contamination, which is important for modern megacities and dusty soil "directions".

If you neglect the replacement of this important component, then the consequences for the motor can be very sad. The engine will begin to experience air "starvation", which will negatively affect not only fuel consumption, but also provoke an overestimated oil consumption. And this already “smells” of an early overhaul of the unit, because the components of the piston group will not take long to wait.
A practical difference between modern elements is the possibility of cleaning them by washing. Thus, the service life of these components is about twice as long as that of traditional filters.

The need to replace the air filter on Largus

It has long been undeniable that the air filter in the air path is endowed with a significant role, because along with its fuel "colleague" it ensures the purity of the mixture sent to the combustion chambers. The power characteristic of the LADA Largus engine directly depends on this factor. The operation of a car provides for an uncontested and gradual clogging of the component we are considering. You should not wait for the moment of complete cessation of the filtering function, because the operation of the motor will be impossible, and the harm to it cannot be overestimated.

Lada Largus with a dirty air filter will be prone to increased fuel consumption and unjustified power reduction. The manufacturer deliberately placed the air filter in the most convenient place. So that the owner is not too lazy to look into it and evaluate the degree of clogging. If the fact of contamination is on the face, then resort to replacement as soon as possible. This work will become feasible even for the owner, who has just embarked on the path of a motorist.

How to replace the air filter correctly?

The procedure on the 8 valve unit has some minor differences from the algorithm on the 16 valve version. This prompts us to describe the sequence of actions for each of the types of motors separately.

Note the general requirement: it is recommended to carry out the replacement when the LADA Largus car is located on a flat area, where there is a sufficient level of illumination. Prepare a container (bag) in advance in which you can dispose of the old filter.

We operate on the 8-valve version

1. We take out the used filter component on version 8 valves.
2. Install a new filter in its place.
3. Close the lid of the box.
4. We tighten the bolts.

How to proceed on 16-valve units?

1. We are looking for the place of "deployment" of the element. It is located in the central part of the compartment directly behind the motor.
2. Here you have to unscrew a couple of bolts holding the filter box.
3. Having loosened the clamps of the air duct, and having removed the protection, it opens the halves of the filter box.
4. For convenience, the body of the element should be taken to the side.
5. We extract the component that has spent its resource to the outside.
6. We install the new component in its original place.
7. Now the body is to be returned to the "legitimate" position.
8. Do not forget about installing the previously removed plastic protection.
9. We tighten the body bolts.
10. We clamp the clamps of the air line and, after checking the tightness of the assembly, we start the engine and enjoy its “free breathing”.

Air filter replacement is complete.

Summing up

As we stated, changing the air filter is so simple that it is not capable of raising any questions. The solution of such issues in the conditions of service stations is a waste of the financial component. Despite the simplicity of execution, this procedure is very important to ensure the correct functioning of the Lada Largus engine. The excellent condition of the element contributes to the “demonstration” by the engine of its declared characteristics, which can only please the owner of LADA Largus.

The air filter in Renault K4M and K7M engines, which are equipped with Lada Largus, is responsible not only for the quality of the air supplied to the combustion chamber, but also for its quantity. A clogged filter, regardless of the engine, will cause air to mix with gasoline in the wrong proportions, resulting in high fuel consumption and failure of the engine control system. Replacing the air filter on Largus is carried out in a few minutes, and the filter is inexpensive, so you should not delay the replacement.

Before choosing a filter for Lada Largus, you need to decide on the engine model. Depending on the year of manufacture, the K7M engines with an 8-valve head and K4M with 16 valves with a capacity of 105 forces were installed on the car. Since 2015, VAZ 8-valve 11189 engines have been installed on some cars, and since 2017 the plant has switched to 16-valve VAZ 21129 engines. Therefore, there are at least four types of filters for Largus. Considering that two VAZ engines were also installed on the Lada Grant, there should not be any problems with them. Renault engines have not retired yet, and the plant plans to install a 110-horsepower Renault H4M / Nissan HR16 aspirator, which was used for some time on the Lada X-Ray.

Filter from an old 8-valve Renault K7M engine

We conclude: for all 8-valve Renault engines K7M suitable air filter 165469466r, and for 16-valve engines K4M you need to buy a filter 8200431051 , until 2016 he had an article 7701045724 . The price of the original is about 10 dollars.

In addition to the original Renault filters, you can buy one of several third-party replacements. For the eight-valve K7M engine:

• COMLINE EAF411;
• CLEAN FILTERS MA1142;
• FEBI 30071 or 31264;
• FILTRON AR131/1;
• KRAFT 1715035;
• SWAG 60 93 0071 or 60 93 1264.

• CHAMPION U724/606, CAF100724P;
• BOSCH 1 457 433 529.

When to change the air filter on Largus

The plant recommends replacing the Lada Largus air filter, regardless of the engine, after a run of 30 thousand km. Nevertheless, a rare filter survives until the middle of this period. This is primarily due to the concentration of dust in urban areas, and if the car is used mainly on a country road, then it is better to shorten the scheduled replacement period. In a word, experienced larus growers recommend not to delay the replacement and carry it out after a run of about 12-15 thousand km. If the filter clogs very quickly, it is better to buy a cheaper option, but change more often.

This filter needs to be replaced immediately.

Signs of a clogged air filter can look like:

1. High fuel consumption, rich mixture.
2. Loss of traction, loss of power.
3. The engine does not develop maximum speed;
4. Heavy launch.
5. Unstable operation of the engine at idle.

You also need to find out which filter element was installed on the 8-valve engine. Until 2012, round filters were installed, after - rectangular ones. The process of replacing them is not much different.

How to change the air filter on an 8-valve Lada Largus

To replace the round filter on Largus, we use the following method:

The rectangular filter is located in the cartridge and is connected to the intake duct by a corrugation. To replace, perform the following operations:

Replacing the filter on a 16-valve Lada Largus engine

Replacing the filter on a 16-valve Largus will also not cause much trouble. To replace, you will need a Torx T25 bit.

Lada Largus cars have been produced since the beginning of 2012. Two types of engines with a volume of 1.6 liters 16 and 8 valves were installed on this model. The factory air filter code is 8200431051. The manufacturer often uses Renault Logan filters with the code 8201153808.

You can replace the filter on all frets yourself. Thanks to the simple design of the filter housing and the accessible location, it is very easy to replace, even without having the literature at hand. Before buying a new spare part, it is necessary to measure the dimensions of the old one, because it often happens that sellers make mistakes and sell the wrong filter at all.

According to the factory recommendations on Ladakh Largus, the filter is replaced after 20 thousand mileage. If the filter is not replaced, the engine begins to “choke” and take oil, which negatively affects the condition of the cylinder-piston system. As a result, carbon deposits may appear on the pistons, and this is a direct road to a major overhaul.

Lada sells modern filters, which are popularly called "nuleviks". These products have a long service life, because they can be washed. The service life of such filters is approximately 50 thousand kilometers.

The engine air filter of your Lada Largus plays an extremely important role in supplying the “heart” of your car with a high-quality air-fuel mixture. The combustion of this mixture in the engine cylinders directly affects the power of the car engine. However, as the filter is used, the working surfaces of the replaceable air filter element become dirty and it simply cannot pass enough air. Imagine a person who is about to run a long distance while trying to breathe through a dirty rag. It is unlikely that such a person will show acceptable results. So a car with a clogged air filter loses its power and you start spending extra money on the purchase of useless fuel.

It is necessary to regularly check the condition of the working surfaces of the air filter and, if necessary, replace the replaceable element. This procedure looks quite simple and can be done even by an untrained driver using a minimum set of tools.

The procedure for replacing the air filter on a Lada Largus car may vary slightly depending on which engine your car is equipped with.

To get started, park your car on a level surface.

Consider the procedure for replacing the engine air filter for a typical engine of the Lada Largus - K4M model.

First you need to remove the intake silencer. To do this, press the spring-loaded latches and undock the exhaust manifold pipe.

Step-by-step instructions for replacing the air filter

• A pipe connecting the brake booster;
• intake manifold;
• Air filter box cap;
• Screw fixing the cap of the air filter box.

1. Wiring block of a stepper electric motor that regulates the idle mode;
2. Throttle Throttle Configuration Adjustment System Wiring Block;
3. Air filter box;
4. Bolts fixing the air filter box;
5. A pipe that captures gasoline vapors.

The procedure for replacing the filter element must be carried out according to the following algorithm:

• Remove the throttle valve configuration adjustment system.
• Remove the pipe indicated in the figure #5 from the box #3 of the air filter.
• Remove the two #4 screws and undock the #3 air filter box from your car. To do this, you need to use a replaceable head type "Torx E8", a knob and an extension.

After removing the air filter box, check the condition of the replacement element and replace it if necessary. Do not forget to clean the filter box from street dirt accumulated in it.
