To achieve optimum performance, combustion engines require clean intake air. If pollutants in the air, such as soot or dust, get into the combustion chamber, pitting may occur on the cylinder heads, causing premature wear of the engine. The function of electronic parts located between the suction and the combustion chamber may also be significantly impaired. 

MANN-FILTER air filters are the end of the road for all dirt particles. No matter whether it's dust, pollen, sand, soot or even water droplets - thanks to the highest degree of dirt separation and high mechanical stability, MANN-FILTER air filters filter even the smallest particles out of the intake air. This enables an optimum composition of the fuel-air ratio and ensures that the engine performance is consistent.

In order to guarantee performance, air filters must be checked regularly, as a blocked filter will impede the air supply to the engine. The possible consequence of this is: the fuel may not be completely burned and may in part be discarded without being used. Here is another hallmark of MANN-FILTER air filters: the high dust holding capacity ensures reliability throughout the entire service interval.

Why Bosch filters should be your first choice

• Bosch is one of the world's leading manufacturers of gasoline and diesel systems, so no one is better placed to specify the right filter than Bosch
• Each filter is made specifically for each engine type, so they are matched to the specific engine requirements without compromise
• Guaranteed standards that meet or exceed vehicle manufacturer specifications
• Improved engine performance and fuel consumption
• Increased service life and reduced engine repairs

For more than 80 years Bosch has been developing and producing filters. As one of the pioneers of injection systems, Bosch recognized the importance of protecting these sensitive systems at an early stage. This expertise has been consistently applied to every filter carrying the Bosch brand.
