Arlen Ness Naked Stage 1 Big Sucker Air Filter 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.

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.


  • Accepts stock air cleaner cover
  • Available with black, chrome or natural finish backing plate

Arlen Ness Naked Stage 1 Big Sucker Air Cleaner For Harley 2014-2016 4.9 5 14 14
Easy install great performance boost I installed this on my 2015 ultra limited prior to a 6 hour trip to DC for rolling thunder. The chapter I ride with is mainly made up of other newer ultras and while they were filling up with 3.6 and 4 gals of gas I was only topping of with 2.8 and 3 gals.. very noticeable improvement in fuel milage. I can safely say I added an additional 40 miles per tank with this product. August 16, 2016
A hidden jewel! Easy to install with very noticeable power, are for sure upgrade. August 14, 2016
AWESOME!!! For a simple air filter I love it! The air filter is so much bigger than the stock piece and you can definitely here it sucking air now. The quality of the base is great. It's heavy and made very well. Install was easy and I love how you can use the stock cover, not really trying to be stealth, but I don't have to worry about needing a rain sock. The back portion of that encases the stock filter is not used so it's free to suck from 360 degrees but it's still covered so if it rains you don't have to worry about a rain sock. The cover does stick out a little further because the air filter is so big, but it doesn't get in the way of anything. Installed this at the same time with V&H FP3, Rinehart Extreme Tru Duals and Accel Stealth Coils. August 7, 2016
easy to install, great flow. I definitely feel the difference in power. easy to install, love the way it can be used with the OEM cover. August 2, 2016
best bang for the buck it arrived promptly from Revzilla. Have not put it on yet cause I been busy. Used another Big Sucker on another bike. July 5, 2016
2015 Street Glide Special At first I did a stage one, but only with the K and N replacement air filter. I always thought the 103 could use more air. I installed the big sucker and the engine came alive. Pulls much harder above 4,000 rpm. Very happy with the quality, fit and finish of this product. May 17, 2016
