Green Filter USA - Round Filter; OD 14", H 4"

Deep pleats in the double-layered cotton create a 10-15% increase in filtration surface. This allows a greater volume of air to move more freely into your engine cylinders while maintaining superior filtration. The specially designed cotton filter traps particles as small as 5 microns. Steel wire mesh encases the cotton filter for strength and dent resistance. The hand-molded, flexible rubber base offers an airtight seal and absorbs vibration. Green Filter USA filters are pre-treated with a specially formulated dirt trapping oil that creates a positive magnetic charge, or ionic bond, with the filters stainless steel mesh. The positive charge attracts negatively charged dust particles, causing them to cling to the steel mesh and allowing the cotton to remain clear for maximum airflow.
