Don’t waste time installing a product that doesn't fit. We worked hard ensuring that this product is an exact fit on the vehicles listed below.
Yes - if you were to select the 2015 Harley Davidson FLHR Road King air cleaner from our fit guide, you'd receive the correct parts to fit your machine. These air cleaners bolt straight in place of the OEM components for a trouble-free installation.
By installing this with a thunder header, do I need to tune bike right away? Thanks in advance.
By Sabb
Yes, we highly recommend the use of an aftermarket ECU tuner upon the installation of an air cleaner kit. Especially if you're using it in conjunction with an upgraded header. The change in airflow requires a significant change in fuel delivery. The easiest tool to use that doesn't require a trip to the dyno would be a Cobra Fi2000R Fuel Tuner. It's easy to install and comes with easy-to-follow instructions that explain step-by-step how to adjust the device to your bike's requirements. Thirty minutes, at most - in the garage to put it on your bike, and by the time you've gone through your first tank of fuel, you should have it dialed in exactly as your bike needs.
Arlen Ness Big Sucker kits are designed to bolt straight onto the OEM carburetor (or fuel-injection system). So long as you have the original carburetor and intake manifold on your machine, you will have no problems fitting this air cleaner kit to any bike you select from the fit guide above.
