Mahle Fuel Filter KL478 (BMW 320D)

Fuel filter modules efficiently prepare gasoline and diesel fuels for the combustion process. For this purpose, they use high-separation filter media and feature an advanced functionality scope. The fuel pressure in gasoline filters can thus be adjusted by a pressure regulator integrated in the fuel filter.

For diesel engines, the functional range of the MAHLE fuel filter modules can be significantly more complex. The fuel can be cooled or heated, for example, or the water content of the fuel can be separated.
