Arlen Ness Big Sucker Stage 1 Air Kit with Beveled Cover for '17-Up Harley-Davidson Touring and '18-Up Softail Models
The new Big Sucker Stage 1 performance intake for Milwaukee-Eight engines adds new and improved features to the original industry-leading air cleaner
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 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
Smooth radius air inlet for unobstructed air flow
New aluminum filter top plate has integrated filter mounting studs for increased durability while eliminating the need for additional filter mounting hardware
High performance filters are made from black pre-oiled cotton for the best in airflow and filtration
Filter is washable and re-usable
Backing plates available in gloss 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
