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.

Arlen Ness Stage 2 Big Sucker Air Cleaner Kit For Harley Twin Cam 1999-2015 4.6 5 5 5
Great all around upgrade. If you're considering a Stage 1 upgrade, this is a great air cleaner to consider. Good band for your buck, classic not overly flashy styling. This will also fit under most stock covers. May 11, 2015
Can't go wrong! Bought this for my 04 HD Springer Softail (FXSTSI) with the hopes to increase power and give it that old school look. I'm more than satisfied with the results. Revzilla had it on sale for lower than anyone else and it shipped ridiculously fast. Ordered it Wednesday afternoon and it arrived with Fridays mail. The Big Sucker looks great and doesn't interfere with my leg while riding. I obviously will recommend installing a fuel tuner or super tuner to get the most out of your bike seeing that you will run lean, more so than from the factory. Overall great product, excellent price, and amazing service from Revzilla.com. April 27, 2015
looks great - a bit wide The breather systems looks great, gives my 2001 dyna a bobber style look which I love, the only downside is that it sticks out really far making an awkward angle for my forward highway peg (my foot is 1/2 off the peg if its straight). I just ordered a set of longer pegs which will hopefully be able to compensate for the wider breather system. April 1, 2015
Exceeded my expectation Great product, easy to install, noticeable HP compliments V-H short shots and V-H FP3... 2014 H-D fat Bob October 7, 2014
Performs well, looks good Very pleased with the performance. More horse power from the better air flow is obvious. The filter itself is holding up well t the Texas dirt and sand. September 24, 2013

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
