This internal air filter from Mann Filter is a replacement element for the engine air intake system of the host tractor. It captures airborne particulate before it reaches the intake manifold, protecting the cylinders and turbocharger from abrasive wear. The filter element is designed to seat in the factory housing with a precise fit that maintains the seal between the dirty and clean air sides. A clogged element restricts airflow, causing a drop in engine power and an increase in fuel consumption. The manufacturer's construction matches the original pleat density and media surface area, which preserves the specified pressure drop across the filter.
