Performance Air Filter Kit - Stage II - Contrast Cut
Enhance your Harley-Davidson M8 engine’s performance and aesthetic appeal with the ARLEN NESS Stage II Performance Air Filter Kit. Designed with a high-flow black pre-oiled cotton media, this filter maximizes airflow by incorporating a pleated top and side intake design, providing over 50% more surface area than factory paper filters. The increased filter height is specially engineered to boost airflow without compromising legroom, resulting in improved engine efficiency and responsiveness.
Constructed from CNC-machined billet aluminum, the filter cover, spacers, and clamps offer durability and a sleek contrast cut finish that complements your bike's styling. The kit includes all necessary components: a performance filter, billet air cleaner cover, four spacers, clamps, and mounting bolts, making installation straightforward. Please note, the kit does not include a backing plate; OEM or Harley-Davidson Ventilator® oval backing plates are required.
Dyno testing has demonstrated potential horsepower gains of up to 3 HP on factory displacement M8 engines and up to 5 HP on 124” big bore models, providing a significant upgrade in performance. Whether you're looking to improve airflow, enhance engine sound, or elevate your bike's visual appeal, this ARLEN NESS kit offers a reliable and stylish solution for serious riders seeking performance enhancements.
