Arlen Ness 10-Gauge Stage 1 Big Sucker Air Cleaner Kit For Harley

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.
