While driving, the vehicle's engine draws in ambient air that is contaminated with dust and dirt particles. These particles are collected in the filter. The air filter is thus particularly stressed during city driving and on the motorway, as the fine dust loads are higher there than elsewhere. Depending on the cubic capacity, the engine draws in between 200 m³ and 500 m³ of air per hour at full load. Over time, the filter becomes clogged, as it has only limited absorption capacity. Regular replacement therefore ensures that the engine's performance is maintained and avoids wear and tear of the mechanical components.
A clean engine air filter is important to ensure high engine performance. This ensures that the engine receives sufficient air and fuel consumption remains constantly low. It also prevents the engine from being damaged by sand, dust or pollen. The smallest particles would otherwise act like abrasive material on cylinders, pistons and bearings and can cause scoring. Other components in the intake duct such as the turbocharger or the air flow meter can also be protected from premature wear by an intact air filter.
The best way to detect problems with the air filter is by a decrease in engine performance. The flow resistance increases and less oxygen reaches the engine. If the air filter is heavily soiled or damaged, this can, in the worst case, cause the engine to fail. This can be avoided if the engine air filter is replaced at the specified intervals.
An air filter has a limited service life and must be replaced after a certain time. Vehicle manufacturers have specified certain intervals for the filters. You will find these in your operating instructions. Depending on the vehicle and the ambient air, the engine air filter may have to be replaced earlier. The air filter should be checked for dirt and moisture, especially after long periods of standing still in the vehicle.
When replacing the engine air filter, it is worthwhile relying on high-quality products to meet the filter characteristics specified by the vehicle manufacturer. The most important quality criteria of the air filter include a high filtration performance, i.e. the separation of large and small particles, and a high dust absorption capacity.
The air filters offered by us meet the above mentioned criteria and partly convince with a very good price-performance ratio. A best example of this are the air filters from Hirscher, which undergo our own quality control before they are delivered to us.

The engine air filter contributes to vehicle safety in 3 essential points:
In addition, the engine air filter also contributes to environmental protection. A quiet engine not only helps the driver concentrate, it also protects the environment from noise pollution. In addition, a clean air filter ensures that fuel consumption and pollutant emissions are reduced. This is a very important aspect, especially with regard to emission limits.
The amount of work required to change the engine air filter is rather low. The filters are easily accessible in most vehicles and no further components need to be removed. The air filter is located in the so-called filter box, which in most models is located on or near the engine. After opening the lid the filter can be easily removed. It is important here that no dirt gets into the intake manifold when changing the air filter! Since the replacement of the engine air filter is not a big deal for a garage, the change is usually favorable. Depending on the vehicle, the replacement takes about 10 to 30 minutes.
A regular exchange of the air filter ensures a constant engine performance, economical driving and the maintenance of the value of your vehicle. If you are unsure, simply contact our customer service with the 17-digit chassis number of your vehicle.
