Arlen Ness Big Sucker™ Air Cleaner Stage I Kit | '17-'20 Milwaukee-Eight


  • 17-up FLT M8 Touring Models w/ Factory Air Cleaner Cover


  • The new Big Sucker™ Stage 1 performance intake for Milwaukee-Eight FLT touring models adds new features to our original industry leading air cleaner and designed to accept your factory air cleaner cover

  • New patent-pending hidden breather backing plate technology is a step up from our original patented system. Each breather is o-ringed at the heads, passes through the backing plate and exits inside the mouth of the throttle body through proprietary breather tubes

  • Our breathing system eliminates oil issues associated with M8 engines by directing any excess breather oil back into the engine. To ensure no oil saturates the filter and restricts your airflow, we also integrated a new patent-pending oil reservoir that can be serviced when you service the filter element.

  • The new aluminum filter top plate has integrated filter mounting studs and directional air venturi for increased durability and performance.

  • Performance filter is constructed from red pre-oiled surgical grade cotton and is washable/re-usable

  • Our filter offers over 200% more surface area then the factory filter and features a tapered bottom resulting in more filter surface area then any other performance intake option designed for the 17-up factory cover

  • Backing plates available in standard, black or chrome finish

  • Each M8 Big SuckerStage I kit includes one-piece backing plate, breather tubes, performance filter, filter top, gaskets, oil reservoir and necessary hardware
