• 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 Brass 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
• 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
