A combustion engine only works with air. So that this air cannot contaminate the engine with dirt particles, it is filtered in advance. Every combustion engine has an air filter that has to be either replaced or cleaned after a certain period of time. In the following we want to go into the function of the air filter and signs of possible defects. We also list the typical time intervals at which replacement or cleaning should take place. We also go into the possible consequences of a dirty air filter. Finally, CarTipsandmore gives a tip for buying these components at this point.

Air filter – what is the actual function?
This component is made of a certain filter material that can filter the air going to the nitro engine in the best way. This prevents dust particles, insects or dirt from reaching and contaminating the motor. Accordingly, the said component is essential to enable a long service life of the engine. If too many dirt particles settle on the filter, it can become clogged over time and not enough air can get to the engine, causing it to lose power quickly. This can be felt by the fact that the acceleration decreases significantly. In most cases, fuel consumption also increases. But if you are particularly unlucky, the engine can fail completely. There are special sports air filters that allow the vehicle to perform better. This is achieved through better air intake. But an increased noise level can also indicate a sports air filter. While some modern sports cars already have a sports air filter ex works, there is also the option of retrofitting. But do not buy sports air filters from dubious dealers. Let specialists advise you as to whether the component is compatible with your vehicle model at all. The quality of the component also has top priority. Therefore, always buy from reputable brands.
What can be signs of defects on the component?
An air filter usually lasts quite a while. But here, too, it is a question of consumables that will eventually reach the end of their service life or at least have to be cleaned. In most cases, typical signs of this are a significantly reduced performance of the engine. Acceleration is then often severely limited. This will be felt immediately when you step on the gas pedal. But an unusual noise from the air filter box can also be an indication that it needs to be replaced or cleaned. In addition, in modern vehicles, the warning light may come on, indicating that the vehicle needs to be replaced or cleaned. The causes of these signs are usually clogged filters or cracks in the product. But even kinked corners and edges can already lead to an error display. If a defect has crept into the filter, if it is dirty or has cracks, this will have direct consequences. As mentioned above, engine performance is reduced. However, fuel consumption then also increases significantly. In the worst case, a component defect can result in damage to the engine or turbocharger. Therefore, immediate action should be taken if there is a suspicion that something is wrong with the component.
How often should the filter be exchanged?
On the whole, an exchange must take place when it is necessary. This means that at the first sign of a possible defect or clogging of the part, you should go straight to a workshop to get clarification.
In addition, the manufacturer of the vehicle specifies in the vehicle manual when and how often the filter should be replaced. A replacement interval or cleaning interval of 40,000 km to 60,000 km is given here as a guideline. However, if signs of defects appear prematurely, action should be taken earlier.
How does the exchange take place and what costs will I incur?
The filter itself is not expensive. This is available for 10 to 60 euros. Since the time required is usually only half an hour, the wages for specialists in the workshop are not particularly high. All in all, 50 to 100 euros can be expected here. Of course, you should only have the component replaced if you have previously compared the prices and seriousness of different workshops. This saves a lot of money.
However, if you have the necessary experience, a certain technical skill and the necessary basic knowledge, you can confidently do this process yourself and carry it out yourself as a DIY job. Of course, the process varies depending on the vehicle model. So find out beforehand in the manual how exactly you have to proceed. There is usually a step-by-step guide here. But in general, the procedure is as follows: the air filter box must be opened. The part can now be exchanged or cleaned. If you are still unsure or have no experience in replacing this component, it is better to seek support from specialists. If the filter is installed incorrectly, this can even result in the engine attracting dust particles and dirt. The consequences would be disastrous for the engine.
The conclusion and a tip from CarTipsandmore
In conclusion, the air filter is incredibly important to a vehicle. Consequently, the part should always be in the best condition. Because only filtered and clean air can ensure an ideal air-fuel mixture and protect the engine from contamination. Decreased performance, increased fuel consumption and strange noises from the filter box are signs that you should inspect the part. It is best to drive to a workshop if you do not have the necessary basic knowledge and experience. The vehicle manual usually states how regularly an exchange should take place. This is usually due every 40,000 to 60,000 km. But if there are signs of defects or contamination, you must act immediately. The exchange itself is quick and doesn't cost much. Your engine and the turbocharger can be spared, while you only have to pay just under 50 to 100 euros. At this point, however, CarTipsandmore strongly recommends only buying high-quality car filters. Popular and renowned brands for these products include Knecht, Filtron and Mahle. Rely on quality so that your vehicle's engine will continue to function smoothly for a long time.
