This engine air filter, part number CF2864 from Mann-Filter, captures airborne particulate before it enters the engine intake. It sits inside the air cleaner housing on the host tractor, where it filters the combustion air drawn into the turbocharger inlet. A clogged filter element increases intake restriction, which reduces engine power and raises fuel consumption. The filter media is pleated to maximize surface area within the housing envelope, and the gasket seals against the housing to prevent unfiltered air from bypassing the element. On installation, ensure the housing is clean and the gasket seats evenly before closing the cover.
