The Arlen Ness Big Sucker Stage I air filter kit is one of the most effective ways to boost the power of your Sportster. By replacing the restrictive factory air cleaner with this high-flow exposed filter and billet outer cover, you allow the engine to breathe much more freely, resulting in improved throttle response and overall performance. The kit is available with either a traditional red oiled filter or a synthetic weatherproof element for those who ride in all conditions. This kit is designed to fit 1988 to present Sportster models, though it is not compatible with the XR 1200. It is a complete Stage I solution that includes the backing plate, filter element, and all the necessary mounting hardware to get your bike back on the road with a noticeable increase in intake efficiency.
