Features:

• BIG SUCKER™ STAGE I AIR FILTER KITS WITH COVER FOR M-EIGHT

• 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
