Air Filters
Task of the air filter
- To protect the engine against dirt particles in the intake of air
- To protect the engine against wear
- To safeguard the air supply in the mixture generation
- To reduce the noise level
Change the air filter regularly according to the vehicle manufacturer's specification!
Consequences of silted-up filter:
- Poor air-fuel mixture generation resulting in reduced engine power and increased pollutant emissions
- Increased fuel consumption
- Increased engine wear from particles
- Problems starting your vehicle
The prerequisite for flawless operation: Tight fit
Leakages and porosity lead to a bypass of unfiltered air (unmetered air) in the intake duct. Consequently, Bosch air filters possess a particularly long-lasting seal made of polyurethane:
- Exact fit matched to the housing shapes
- Unevenness in the housing is compensated
- Flexibility and suppleness in the seal across the entire service life of the filter
