Arlen Ness 18-459 Black Backing Plate Stage 1 Big Sucker Harley Touring M8 17-Up

• New Big Sucker™ Stage 1 performance intake for Milwaukee-Eight™ FLT touring models adds new features to the original industry-leading air cleaner and designed to accept factory air cleaner cover
• New patent-pending hidden breather backing plate technology is a step up from 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
• Breathing system eliminates oil issues associated with M-Eight 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
• 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
• 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 natural, black or chrome finish
• Each M-Eight Big Sucker™ Stage I kit includes one-piece backing plate, breather tubes, performance filter, filter top, gaskets, oil reservoir and necessary hardware
