Engine air filters

Air filters in the car ensure safety and value retention

Air filters clean the air that is passed on to the engine for the combustion process. To ensure consistent engine performance, vehicle manufacturers therefore recommend regular filter replacement. For this reason, the engine air filter is generally replaced at each inspection.

It is also worth relying on the high quality of the original parts for this filter. That's why you'll find original filters from vehicle manufacturers for all common vehicles. How important the air filter insert is, how it works and what it contributes to the safety and value retention of the vehicle, we have summarised for you in the lower section of this page. Also, we will give you advice that will be helpful when buying air filters.

How does an engine air filter work?

Depending on the engine capacity, the engine of your car sucks in between 200 m³ and 500 m³ of air under full load. The air filter catches the air contaminated with dust and dirt particles while driving, cleans them and passes them clean to the engine. This process is particularly important to ensure the best possible engine performance and to avoid premature wear of mechanical components.

A good air filter should therefore have the following properties:

Good filtration capabilities (separation of large and small particles)
High dust pick-up capability

The air is more or less polluted depending on the weather, season and environment. For example, the engine air filter is particularly stressed during city journeys, as the fine dust pollution is higher there than in the countryside. Depending on the vehicle and load, the air filter should be changed every 30,000 km - 40,000 km. For seasonal vehicles or other vehicles with longer service lives, it is advisable to check the filter for contamination and moisture before the first drive. If the air filter insert is too dirty or too wet, it should be replaced at this point.

Why does an air filter provide safety and help protect the environment?

In the meantime, high-quality air filters meet ever higher quality standards and thus meet increasing legal requirements. For example, the filter element must be constructed in accordance with flame protection specifications. This prevents, for example, a burning cigarette butt from being sucked in and poses a danger to the car and its occupants.

The engine air filter also filters the engine intake noise to help the driver concentrate on the road. In addition, an impeccable and high-quality air filter insert ensures optimum fuel combustion. This in turn protects nature and contributes to compliance with emission limits.

Damage caused by a non-observed replacement interval of the air filter often results in high repair costs. Premature signs of wear can be detected early during regular vehicle inspections. A complete cheque booklet not only increases the value of your car in the event of a possible resale, but also ensures that the installed parts function perfectly.
