K&N Performance Air Intake Boosts Power in Many 2008-2013 Twin Cam Harleys®
K&N Performance Air Intake Boosts Power in Many 2008-2013 Twin Cam Harleys®
4 May 2017
Everything needed for bolt on performance is included in the RK-3930X kit
Think for a moment about Clark Kent or a wolf in sheep’s clothing. There is something very exciting and satisfying about stealth power. For those who want more punch from their twin cam Harley-Davidson® in a stock-looking package, the new K&N RK-3930X performance intake system is just the ticket.
In K&N’s rigorous, controlled dynamometer testing, the RK-3930X provided nearly 6 additional horsepower in a stock 2013 103CI Harley® Street Glide. That estimated power gain was realized at a real-world riding sweet spot of 4400 RPM.
Just as impressive is the estimated torque boost of over 7.5 ft-lbs in the same 2013 Glide using the new RK itake. That peak gain was delivered at just over 3800 RPM. That is the kind of performance enhancement in the power band’s mid-range that will provide arm-stretching off-the-line acceleration.
The RK-3930X is designed with an innovative mounting plate and velocity stack
Those estimated power gains come in an innovative package that hides the intake magic behind the stock H-D® air cleaner cover. So what is the magic you ask? The RK Series assembly in the RK-3930X features an innovative powdercoated billet aluminum back plate that eliminates external breathers. At the intake’s core is a built-in, dyno-tuned velocity stack.
Of course, the intake includes a filter element that is constructed of K&N’s world-famous cotton gauze filter media. The pleated, oil-impregnated filter media allows a marked increase in air flow, while providing extremely efficient and reliable filtration.
The filter element is fully washable and reusable, eliminating the need to buy and dispose of paper filter elements. That makes sense for your pocketbook and for the environment. All that is needed for easy and effective filter recharging is a K&N cleaning kit like the 99-5000.
The RK-3930X sits behind the stock Harley intake cover
If you like your power delivered in an understated form, the RK-3930X may be the intake option for you. Check the application list below or consult K&N’s convenient online application tool.
