This external air filter is an original AGCO component designed for the engine air intake system of agricultural tractors. It removes particulate from the incoming air before it reaches the turbocharger and combustion chamber. A clogged or damaged filter restricts airflow, causing a drop in engine power and increased fuel consumption. The filter element is constructed to match the housing dimensions of the original assembly, ensuring a proper seal and preventing unfiltered air from bypassing the element. On installation, verify the sealing surfaces are clean and the housing is fully closed to maintain system integrity.
