Many major automobile and engine manufacturers rely on the expertise of MAHLE for air filters—for good reason: engine performance, torque, low consumption, and minimal emissions require well-filtered air. And our cellulose (paper) filters, plastic non-wovens, or a combination of both can trap just about everything. They capture up to 99.98% of toxic dust, soot, and tyre particles. The finest filters trap nearly all particles larger than 3 µm. This means that MAHLE air filters prevent premature wear of valves, cylinder surfaces, piston rings, bearings, and other engine components. But be careful: in order for the filters to work perfectly, they must be replaced at the intervals prescribed by the automobile manufacturer.

In order to protect the filters from moisture, the intake port is designed to keep water away from the filter element as much as possible. If moisture does reach the filter anyway, we have added another layer of protection. Our filter papers are impregnated with a special synthetic resin that increases the resistance of the filter insert to water and chemicals. 

MAHLE oil filters—doorman of the engine

MAHLE oil filters reliably prevent contaminants from entering the lubrication system and maintain oil quality as well as the 

performance and efficiency of the engine. Thanks to stable pleat geometry, cold start stability is assured. Load peaks up to 20 bar 

are compensated due to the high pressure resistance of the housing. A pressure relief valve guarantees the oil supply under all 

conditions—for viscous oil encountered during cold starts or at low temperatures, for extremely contaminated filter elements, or 

when the replacement intervals have been exceeded. A non-return flow valve prevents the draining of the filter when the engine is 

switched off and ensures adequate oil supply when the engine is started. High-grade sealing materials and custom-fit connecting 

pieces assure reliable separation of contaminated and filtered oil.

However, an important consideration for optimum functioning of oil filters is that filters are replaced within the maintenance 

intervals stipulated by the automobile manufacturers.
