Arlen Ness Stage 2 Big Sucker Air Cleaner Kit For Harley Twin Cam

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. 

The air filter elements 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. 

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 than the pink/red hue of the Standard Filter.

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

The Stage 2 kit differs from the Stage 1 by including a 20% larger air filter element.

Note: Air cleaner images are for reference only. All kits on this page will include filter of your choice.

A shopper asked: I have a 2013 fat boy lo and I put rinehart 2 to 2 churchill exhaust and a stage 1 air cleaner. I am looking at putting vance and hines big shot staggered on. I will also put the v & H fuel pack on as well. I am wondering if I put on the Arlen Ness Stage 2 air cleaner, will I see a difference or should I just keep the Harley stage 1. I would really like to change the look but will it be a difference? Mar 26, 2015

Bob G: I bought a Stage 2 Big Sucker in late fall 2014, and because I live in the Midwest, haven't been able to put too many miles on my Softail Deluxe since. That said, I can say that on a recent ride to Wisconsin, I was very satisfied with the HP, feel, and acceleration in comparison to before. Whether it makes a HUGE difference is debatable, but if you factor in the look--the appearance is unbeatable, it really stands out--it may be worth it to you. I don't regret having shelled out the money for it. Hope this helps. Mar 27, 2015
