These air cleaners have an updated look with powder coated finishes and optional pre-oiled washable filter elements. Choose from flat black, orange, blue, silver vein, or a traditional chrome finish. The pre-oiled washable filter elements flow more air than standard paper elements and are color keyed to provide a great look that matches the powder coated finish. Each kit includes the filter assembly with filter element, mounting stud, knurled nut, PCV (positive crankcase ventilation) or smog adapter & hardware.
