This main air filter is an original AGCO component designed to protect the tractor engine by removing particulate and contaminants from the intake air stream. It sits in the air intake housing upstream of the turbocharger and intake manifold; clean air delivery prevents abrasive wear on piston rings, cylinder walls, and turbocharger vanes. A restricted or overloaded filter reduces airflow, causing a drop in engine power and increased fuel consumption. The filter element is constructed to match the housing’s seal geometry, ensuring no unfiltered air bypasses the media. On replacement, verify the housing gasket is clean and seated, and tighten the retaining clips to specification.
