With five layers of progressively finer mesh cotton gauze media between 100% 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 spaced 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. The air filter is wrapped in reinforced metal providing maximum strength to prevent filter collapse.
