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. Glue beads on the backs of the folds help the filter elements retain their shape.

A failure can make itself noticeable as follows:

- Increased fuel consumption

- Reduced engine power

- Error code: Fuel mixture preparation/exhaust gas treatment

Causes for a defect could be:

- Filter heavily soiled (construction site operations)

- Replacement interval exceeded

The oil filter module is flange-mounted to the side of the combustion engine and incorporates an oil cooler and the housing for the oil filter insert. Ducts in the module initially direct the engine oil to the oil cooler. The oil cooler is designed as a plate heat exchanger, comprising multiple profiled aluminum plates soldered together. The plate heat exchanger has four connections, two of which serve as the inlet and outlet for the engine oil, and the other two as the inlet and outlet for the coolant circuit. The engine oil circulates in the gaps between every second plate, and coolant is pumped through the other gaps. The profiling and quantity of the plates ensure an extensive surface area for efficient heat transfer, while maintaining a compact heat exchanger design.

From the oil cooler, the engine oil passes through the oil filter, which cleans the oil. Once cleaned, the engine oil is returned via ducts in the module to the engine, where it supplies all moving parts that need to be lubricated or cooled.

A failure can make itself noticeable as follows:

- Filter medium has come loose from the end plate

- Filter is clogged

- Filter paper is torn

Causes for a defect could be:

- Oil change interval exceeded

- Filter not replaced during oil change

- Engine oil overheated (tuning, cooling system malfunction, etc.)
