This external air filter element is installed in the engine intake system of the host tractor. It captures airborne particulate before it enters the air intake manifold, protecting the turbocharger and combustion chamber from abrasive debris. A restricted element reduces airflow to the engine, causing a drop in power output and increased fuel consumption. The filter is designed to seat correctly in the housing, maintaining the seal that prevents unfiltered air from bypassing the media. On replacement, ensure the housing sealing surfaces are clean and the filter is fully seated before closing the cover.
