The Arlen Ness Performance Air Filter Kit Stage 2 Contrast Cut delivers increased airflow and aggressive custom styling for your 2017-2023 Milwaukee-Eight Touring or Trike model.

Upgrade your breathing and performance with this proven Arlen Ness design.
Enhance your Harley-Davidson M8 engine's performance and style with the ARLEN NESS Stage II Performance Air Filter Kit. This kit features a high-flow black pre-oiled cotton media filter with a pleated top design that maximizes airflow by drawing air from the sides and top of the filter, ensuring optimal engine breathing. The filter's increased height is specifically engineered to boost airflow without compromising legroom, allowing for smoother acceleration and better overall engine efficiency. The entire assembly includes CNC-machined billet aluminum components—filter cover, spacers, clamps, and mounting bolts—providing durability and a sleek contrast cut finish that complements the bike's aesthetic. With over 50% more surface area than standard paper filters found in factory oval air cleaners, this upgrade delivers significant airflow improvements, which dyno testing has shown can result in up to a 3 horsepower increase on factory-displacement M8 engines and up to 5 horsepower on 124-inch big bore models. The kit includes a high-performance filter, billet air cleaner cover, four billet spacers, clamps, and mounting hardware, but does not include the backing plate, which must be compatible with OEM or Harley-Davidson Ventilator® oval backing plates. Installing this kit not only boosts engine performance but also adds a stylish, aggressive look to your motorcycle, making it a perfect upgrade for riders seeking both function and style.
