Arlen Ness Big Sucker Air Filter Element for 2017-2025 Harley-Davidson M8

Factory 114 and 117 air filter housings are pretty open—but the flow can be improved with a less-restrictive air cleaner element.
  • Air filter upgrade is built specifically for factory Ventilator oval air cleaners using the larger Milwaukee-Eight engines
  • Made from high-flow black pre-oiled cotton media wrapped in a stainless-steel jacket
  • Increased filter height increases airflow, but fits the factory backing plate and outer cover 
  • Over 22% more air filter surface area than filters found in factory oval air cleaners
  • High-flow performance filter media improves air flow
  • Dyno tested; offers up to a 3hp increase after installing on 114" and 117" M8 engines and up to 5hp gain when installed on 124” M8 engines
  • Each filter includes all necessary components for easy, complete install
  • CA-friendly—exempted under California Air Resource Board exemption D-639-10
