A timeless classic

As Harley Davidson as leather jackets and loud pipes, these things will never go out of style. Built like a tank and capable of flowing more air than you'll ever need. What's not to love? If you're wondering if this is the right air cleaner, yes, it is.

Added Performance & Classic Slick, Sleek Look

The understated good looks of this air cleaner kit packs a powerful punch in added performance for your bike and is what makes the S&S Super a classic. An air cleaner kit gets you only half the way to added performance, clearly you need to accompany it with a fuel management system or tuner so your engine can optimally process the increased airflow. When I installed the S&S Super, which was easy and straightforward (also see the Reveille video on this), I noticed a meaningful pick up in torque and horsepower. It was like I was riding a different bike, one that was faster and more responsive. No fancy bling with this air cleaner kit, just timeless and classic beauty and performance.

Looks and works great!

S&S is a classic air cleaner and there's a reason for that. It looks great on my Deuce and adds to the overall look of the bike, IMHO. Very well made with all the parts necessary to install and very easy to do. Very happy with the purchase and the look of the product.

Quality fitment.

Everything I had expected. Easy to install. Extremely well made and definitely lives up to the tear drop air cleaner reputation.
