This external air filter element is a replacement for the engine intake system on a range of harvesting machines and agricultural tractors. It is installed in the main air cleaner housing upstream of the turbocharger inlet. The filter media captures airborne particulate before it can enter the combustion chamber, protecting the cylinder liners, piston rings, and turbocharger compressor wheel from abrasive wear. A restricted element causes a drop in intake pressure, which can increase fuel consumption and reduce engine power output. As an original-equipment specification part from Mann-Filter, the pleated paper media and seal geometry match the housing's sealing surface to maintain the specified filtration efficiency. When replacing, ensure the housing is clean and the seal seats evenly before closing the cover.
