Arlen Ness Stage 1 Big Sucker Stainless Jacketed Filter Air Cleaner Kit For Harley CVO

Arlen Ness Stage 1 Big Sucker Stainless Jacketed Filter Air Cleaner Kit For Harley Touring Models with 58mm Screamin' Eagle Throttle Body 2008-2013

Arlen Ness, the "King of Choppers", knows a thing or two about performance. The Big Sucker is the best-selling and most powerful air cleaner kit on the market - period. Simply, the Big Sucker is designed to give your engine maximum airflow for maximum performance. Testing shows that by simply installing a Big Sucker kit, horsepower gains of up to 21% are attainable.

Big Sucker kits feature patented, hidden breather backing plate technology - this means the breathers are incorporated into the air cleaner housing itself. Gone are unsightly external hoses and hardware, giving your bike a super-clean look.  Each hidden breather has a sealing O-ring at the heads and exits at the carburetor or throttle body inlet to provide efficient internal engine pressure relief. 

Air Filters are made one at a time using the finest materials available. Filters are all pre-oiled, and feature four layers of surgical-grade cotton to promote airflow and filter air effectively. The filters are hand-poured one at a time in a urethane body, unlike many other filters that are spun, which can leave a residue on the filtration media. 

All kits include a Big Sucker backing plate, high-flow filter, chrome banjo bolts, gasket, hardware, and simple instructions. 

The Stainless Jacketed Filter differs from the Standard Filter in two areas:  The mesh supporting the gauze is made of a rust-resistant stainless steel as opposed to standard carbon steel, and the cotton filtration gauze is in its natural (white) color, rather then the pink/red hue of the Standard Filter.
