With five layers of progressively finer mesh cotton gauze media between 100-percent polyurethane top and base, this high flow oiled conical performance filter provides excellent airflow for maximum horsepower and torque. Washable and reusable for multiple cleanings, the tall, open, evenly s paced pleats provide excellent dust holding capacity for longer service cycle between cleanings. Pliable polyurethane flange with integrated bumps insures tight, no leak seal over the life of the filter.
