K&N Air Charger air intakes for select Harley-Davidson touring, Softail, Twin-Cam and Sportster motorcycle models increase power by eliminating the restrictive stock OE air cleaner and replacing it with a K&N high-flow air filter and cast aluminum intake tube. These intakes come with an die-cast aluminum throttle-body mounting plate and mounting hardware. K&N high-flow intake systems give your Harley an aggressive appearance while providing a significant increase in airflow resulting in more power. These K&N air intakes are street legal in most States. They are not legal for use in California and other States adopting California emission standards.

The quality just wasn’t there with this product. The fit and finish of the product was horrible, and seemed very cheap in quality. Unfortunately I had to return within hours due to a broken stuff after a the first 1/2 hour trial run. Very disappointing. For the price, I definitely recommend considering other options on the market. Unfortunate, as I have been a loyal K&N customer for many years for many different applications.

I rings don't fit. Instructions tell you to use grease to hold them in place, but the don't provide any. Went and bought correct size rings and they stay in place without grease.Some bolts are really hard to get to causing the thin powder coat to get scratched when working spanners.

A little bit difficult to install. The cutouts around the flange are very shallow and hard to get a wrench on them. Made a difference in performance and starting the motorcycle.

The neck of the air cleaner uses double end bolts that you screw half way into the housing the other half stick out and are secured with close end bolts. After riding I checked the bolts are recommended and tightened. one of the threaded bolts sheared off and is inside the housing where it cant be extracted. I did not over tighten or use any amount of force. Very disappointed especially since K&N has been around so long. Not sure what to do now since essentially it's a a $300 paperweight.
