Arlen Ness Naked Stage 1 Big Sucker Air Filter For Harley Sportster

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.

The air filter elements are made one at a time using the finest materials available. The red hue 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. The Big Sucker air filter kit features a one-piece aluminum backing plate and eliminates the need for banjo fittings, hoses and a filter. The breather exits at the mouth of the throttle body, creating a virtually closed-loop system.

Features:

• Hidden breather technology built into backing plate
• High-flow standard or synthetic air filter
• Accepts stock air cleaner cover
• Chrome banjo bolts
• Gaskets, hardware and simple instructions included
• Made in the USA

Note: Kit uses your OEM cover and does not include one. Image is for reference only - actual product may vary.
