This external air filter is a primary intake component for the engine of the host tractor. It is positioned in the air intake system upstream of the turbocharger or intake manifold, where it removes airborne particulate before it enters the combustion chamber. A restricted or contaminated filter element reduces airflow, causing a drop in engine power and an increase in fuel consumption. The manufacturer produces this component to the same pleat density and media surface area as the original assembly, which maintains the specified pressure drop across the intake system. On installation, ensure the sealing surfaces are clean and the housing clamps are tightened evenly to prevent unfiltered air from bypassing the element.
