Let Your 1999-2016 Harley-Davidson® Breathe Deeply with the K&N RK-3932X Air Intake

K&N RK-3932X intake system for Harley-Davidson motorcycles

The simple and clean design of the RK-3932X intake looks great on all Harleys

Harley-Davidson® motorcycles that have undergone a custom engine build or are pushing a large displacement, pose problems for standard or stock air boxes and filters. The factory box and a conventional filter simply can’t provide the flow rate to keep up with the performance of that more extreme build or larger engine. Enter the K&N RK-3932X. That X at the end of the product number indicates that the filter is of an extra tall design that is engineered to keep up with your engine’s performance air needs. An estimated 7 horsepower gain has been verified in dynamometer testing when running the intake.

K&N’s engineers are world renowned for not only designing intakes that are industry topping in performance and filtration, but are also user friendly. That extra tall air filter in the RK-3932X easily mounts to your Harley® via a custom aluminum backing plate that mounts directly to the throttle body and incorporates an aluminum integrated, internal-run breather system. The beefy rubber mounting gasket helps absorb the iconic vibration that makes Harleys what they are. An intake that shakes off your V-twin is not going to do you much good.

K&N RK-3932X parts included in box

The carefully engineered system is easy to install

K&N’s attention to detail in the engineering of the intake does not stop there. The RK-3932X features a clean and simple cover design that accentuates the style of any Harley. The chrome and black motif is attractive and designed to stay that way. The intake is equally at home on the open road or on display at a custom bike show. Of course, the RK-3932X is designed to show off the instantly identifiable and universally respected K&N oiled cotton gauze filter media.

While we are speaking about that filter media, the RK-3932X features a washable and reusable filter cartridge that will save you big money over the miles and years that you own your Harley. You simply need to clean and re-oil the filter yearly (or more often if you wish) and reinstall. The added benefit to the design is that you will not be filling our over-stuffed landfills with dozens of disposable filters. The American-made filter comes with K&N’s legendary Million Mile Limited Warranty.

There you have it. Don’t make your custom built or large displacement Harley suck air through a straw. Open up its lungs (or jugs) with the RK-3932X, which is designed for heavy breathing! Make sure to find the correct intake, air filter, and oil filter using the K&N search by vehicle tool.
