K&N increased power for 2013-2015 Softail models by replacing the stock assembly with an open element high-flow K&N air filter, and bolted-in velocity stack, mounted to a powder coated aluminum backing plate

The Harley-Davidson^® Softail^® family of motorcycles pays tribute to early hard tail Harley-Davidson motorcycles that pre-date the 1958 Duo-Glide. The classic hardtail look is accomplished by tucking the rear shock absorbers underneath the transmission while a triangular swingarm pivots at the top near the rear seat. Harley-Davidson has utilized the Softail design to build bikes that give the appearance of a stripped down chopper, like the FXSB Breakout, or for the timeless look of the Harley FLST Heritage Softail. No matter whether a Softail is ridden like a bare-bones hotrod, or a classic leather bagged touring bike, a little extra power is always a good thing.

The 2013, 2014, and 2015 Harley-Davidson Softail family of big twin motorcycles is powered by the Twin-Cam 103 cubic-inch engine. The Twin-Cam engine was first introduced in 1998 (1999 for Softail models) and has evolved over its 17 year production life. Displacement has increased from 88 cubic-inches, to 103. The traditional single carburetor has been updated to modern fuel injection. Some Twin-Cam engines even feature twin cooling with hidden radiators designed to cool the cylinder heads without upsetting the classic look of a Harley V-Twin. Yet despite these advances in technology, these bikes are equipped from the Milwaukee factory with a rather low-tech and restrictive air filter and air cleaner housing design.

The custom K&N 2013-2015 Softail air cleaner backing provides a solid mounting surface and an integrated crankcase breather system for a trick look that keeps crankcase blow by where it belongs

K&N RK Series air cleaner for 2013-2015 Harley Softails, including the Breakout, Deluxe, Fat Boy, & Heritage remains hidden behind the stock cover so only you and your passenger feel the difference

Similar to Harley-Davidson’s technique of improving upon their motorcycles without interrupting the classic American V-Twin look, K&N^® RK Series performance air cleaner assemblies will provide upgraded performance without disturbing a bike’s heritage. K&N accomplishes this task by replacing the enclosed air cleaner assembly with an open element washable/reusable high-flow K&N air filter, and bolted-in velocity stack, mounted to a black powder coated aluminum backing plate.

The custom K&N backing plate included with 2013-2015 Softail air cleaner RK-3942 does more than provide a solid mounting surface as it incorporates an integrated crankcase breather system for a trick look that keeps crankcase blow by where it belongs. The entire K&N RK Series Performance air cleaner for 2013-2015 Harley-Davidson Softail models, including the Breakout, Deluxe, Fat Boy, and Heritage remains hidden behind the factory Harley air cleaner cover to ensure only rider and passenger can feel the difference.
