Introducing the Fuel Moto AC/DC Stage 1 Air Cleaner. This air cleaner is designed to work either open with the provided billet aluminum cover or use the stock OEM air cleaner cover (requires optional adapter). As with all Fuel Moto parts, our kits include only the highest quality components. The included air filter element features a cleanable cotton/gauze high flow material that is pre-oiled and ready to be installed. The included hardware is of OEM quality. Although installation is very straight-forward, we have made it even easier with the technician created step by step instructions.
