Stage 2 Performance Oval Filter Kit
Dublin, California based Arlen Ness Enterprises' new Stage 2 performance oval filter kit for the factory H-D oval air cleaners "both increases performance and adds style."
Featuring a performance filter with a pleated top - to take in air from the sides, top and front of the filter for maximum airflow - the filter cover, spacers and clamps are all precision CNC- machined from high strength, lightweight billet aluminum.
The performance air filter is made from high-flow black pre-oiled cotton media with increased filter height specially designed to increase airflow without reducing leg room.
Ness claims almost 50% more air filter surface area than the paper filters found in factory oval air cleaners, with dyna testing showing up to a 3 hp increase after installing the upgrade filter on factory displacement M-8 engines - and up to 5 hp gain for 124" big bore M-8 engines.
Kits include a performance filter, billet air cleaner cover, billet spacers and clamps. Available in black anodize finish, they fit oval Screamin' Eagle 'Ventilator' air cleaners and M-8 special/ST models equipped with H-D oval 'Ventilator' air cleaner backing plates. Multiple finishes, including red, gold, chrome and Contrast, will be available soon.
