The RK-3932XB intake on a Harley-Davidson |
Harley-Davidson motorcycles often respond more profoundly to simple performance modifications than motorcycles with other engine configurations. In stock form, Harley-Davidson engines are “under stressed.” What that means is that the engines are designed for a rather conservative balance between reliability and pure performance.
That’s where K&N’s RK-3932XB comes in. The product is one of K&N’s Street Metal series high-flow air intake systems. In short, the system helps your Harley® breathe freely resulting in a potentially substantial power advantage. The RK-3932XB is a complete intake system that replaces the restrictive stock unit. The air filter in the system is extra tall, which markedly increases airflow. The oiled cotton gauze filter media not only increases flow, but it also extends service intervals. You know you’d rather be riding your Harley than servicing it.
Installation of the RK-3932XB could not be more straightforward. The custom aluminum backing plate and vibration absorbing gasket fit securely to the throttle body and feature an internal-run breather system. Once installed, you can realize an estimated 7 horsepower gain at 4662 RPM (as dyno tested on a stock 2016 Harley-Davidson Dyna Switchback 103 ci). That performance boost is the kind you’ll feel instantly. Interestingly, that horsepower gain is more than the first Harley-Davidsons produced in total! The intake unit is especially well suited for custom or large engine builds that truly need that extra airflow.
The clean lines of the RK-3932XB intake system |
The air filter unit on a Harley is a centerpiece of the engine design so it has to be good looking. The RK-3932XB has a subtle, clean appearance. The iconic K&N red-oiled filter media is visible behind the understated black intake cover. The overall aesthetics of the intake speak to its “all business” design and performance.
It should be noted that over the life of the motorcycle, a K&N washable filter is a cost effective alternative to restrictive, disposable filters. Moreover, in a time when our landfills are being loaded with throw-away maintenance items, a reusable K&N filter such as the E-3986, which is the part number for the filter, is an environmentally responsible choice.
The RK-3932XB is made in the USA and is covered by K&N’s exclusive Million Mile Limited Warranty. With easy installation, proven power gains, extended service intervals, good looks, and legendary K&N quality, the RK-3932XB is a great option for Harley-Davidson owners who want more out of their V-twin.
The RK-3932XB is simple, bolt-on performance for your Harley |
