Comfortable conditions in the interior of modern cars are provided by various systems, including conventional cabin ventilation. It is present in almost every vehicle, including the French model Citroën C4. And one of the main elements of the ventilation system is a filter that cleans the air from outside from impurities, dust and pollen.
Some of the most effective options also provide protection from gases. However, over time, even they become contaminated, after which the Citroen C4 cabin filter is necessarily replaced - a job that will take no more than 10 minutes.
How often do you need to replace?
There are several ways to find out about the need to replace the cabin filter:
- looking into the technical documentation of the vehicle;
- taking into account the operating conditions of the model - from the speed limit to the number of stops while driving;
- focusing on the emerging signs of a dirty filter.
The average recommended installation period for new filter elements for most passenger cars, and for the C4 model, is about 15,000 km. Under normal conditions of use (good road, average speed, no traffic jams), this figure can be used as a guide.
If the car is operated in areas with a polluted atmosphere or dusty roads, the period should be reduced by about 1.5 times. Indeed, under these conditions, the filter reduces the efficiency of work after 10 thousand km.
There are a number of signs by which you can understand the need for premature replacement of the filter element. These include the appearance of unpleasant odors in the cabin, even if the filter is multilayer and contains activated carbon.
It is worth paying attention to the deteriorating microclimate in the cabin - a decrease in temperature in winter and its increase in summer. Another indicator that does not seem too significant to many car owners is window fogging, which worsens the safety of using a car.
Cabin filter selection
Giving preference to one of the options, first of all, they pay attention to the original filters and recommended analogues:
- the manufacturer recommends using the Big GB-9877/C carbon filter element;
- as an analogue, you should choose parts with numbers E146034, 6447NV, 6447KL, 647932 and 647975;
- the same parts are used for Citroen C2 and C3 models.
Filters for C5 may not be original - sometimes a suitable option may simply not be on sale. In this case, it is worth choosing any suitable and, if we are talking about saving, an inexpensive option. And preference should be given to either a simple single-layer filter, or a multilayer complex one, which includes activated carbon.
The single-layer filter element provides effective protection against dust and small particles. To prevent the appearance of odors in the cabin and the ingress of harmful gases with the help of such a filter will not work. And its important advantage is the affordable price. The adsorbing properties of coal allow multi-layer filters to get rid of most of the harmful substances contained in the air and even disinfect the air flow entering the passenger compartment from microorganisms.
Instructions for replacing the cabin filter on a Citroen C4
To replace the old filter element with a new one, you will need a regular straight screwdriver and a tool for removing plastic clips (for example, pliers). Having prepared these tools, perform the following work:
- Remove the plastic soundproofing that covers the filter element and closes the neck of the coolant reservoir. You can find it under the hood of Citroen;
- To remove the plastic, carefully dismantle the clips (depending on the year of manufacture of the C4, there may be 2 or 3 of them) and bend the soundproofing, gaining access to the filter cover;
- Remove cover;
- Remove the old dirty filter element and install a new one.
Having carefully replaced the cabin filter on your own with a Citroen C4, it is worth assembling in the reverse order, which will take even less time than disassembly. After completion of the work, the effectiveness of the new part is checked, making sure that the air is fresh again and the system is efficient. Although, if the filter element is non-original, it will also have to be cut before installation.

The air filter of your Citroen C4, despite its not very presentable appearance, plays a very important role in ensuring the quality of the engine. Without it running smoothly and efficiently, your engine will be like the heart of an athlete who sets out to run a long distance in a faulty, mud-filled gas mask.
Agree, it is unlikely that such a competitor will win a convincing victory. So your engine with a clogged and dirty air filter will sneeze and cough, but will not develop the required power. Replaceable filter elements of this design can be made of various materials. For example, an air filter can be made of paper impregnated with a special adsorbent.
Between the fibers of such paper there are pores through which air molecules successfully pass, but larger molecules of dirt and dust linger. Also, the air filter element can be made of synthetic fine mesh material. In any case, the replacement element of the air filter must successfully perform two seemingly opposite tasks: to let the amount of air into the engine cylinders sufficient for its normal operation and to retain dust and dirt from the atmospheric air flow.
Just like that, without filtration, atmospheric air cannot be delivered to the engine cylinders. Well, if you are driving through a birch copse with fresh and clean air, then the air filter carries a minimum load. But when driving in dense city traffic with a gassed and dusty atmosphere, your air filter works hard, trapping dirt and dust. These entrapped particles burn in the cylinders and form additional carbon deposits, which significantly reduce the power of your engine, and their sharp edges can scratch the walls of the cylinder and the working surfaces of the pistons. causing them to wear out.
You can check the condition and replace the air filter on a Citroen C4 model car on your own, without resorting to the services of craftsmen from service stations.
Step-by-step instructions for replacing the Citroen C4 air filter
The air filter box itself is located under the hood in the engine compartment. First of all, disconnect the battery terminals, turn off the power to the car. Then disconnect the air intake pipe.
Carefully detach the airflow filter housing from the propulsion system. There is nothing holding him back now. To remove the filter box cap, unscrew the 6 screws located along the perimeter of the housing. Remove the air filter element. Thoroughly clean the filter seat from accumulated dirt, and then place a new replacement element on the seat.
Despite its modest appearance, the air filter plays an extremely important role in ensuring the smooth and durable operation of the engine system. Therefore, it is necessary to pay special attention to its timely replacement.
By itself, replacing the Citroen C4 air filter is not difficult and can be done independently, but first, let's figure out what kind of work it does. If the filter is old, worn out and dirty, then the motor will not be able to work clearly and develop full power. Unfiltered air must not in any way enter the engine cylinders of the Citroen C4. It's one thing if you are racing along a good road, somewhere in a forest with the cleanest air - then the air barrier will be minimally loaded.
But, if you are on the road in a big city, where the atmosphere is heavily polluted, then the filter works to the limit of its strength, trapping microscopic particles of dirt and dust. These particles, during combustion, will form carbon deposits, which will significantly reduce the efficiency of the engine, and their hard edges may well damage the walls of the cylinders and pistons, which will cause their premature wear.
Citroen C4 car filter
Today, filters for the Citroen C4 can be made from a variety of materials. For example, from paper, which is impregnated with a special adsorbent composition. There are pores between the fibers of this paper and air molecules pass through them safely. At the same time, much larger dirt and dust molecules are retained and filtered out.
