K&N AirCharger 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 mandrel bent aluminum intake tube.

K&N 63-1126 Air Intake Product Reviews

Easy install, noticeable performance upgrade. Also looks amazing on my 2012 Harley Forty Eight.

I ride my Sportster very hard and have put this intake to the test both on the street and in the dirt. A hi-flow killer design that screams performance with plenty of clearance for your legs/knees with mid or forward controls. The filter element has held up great after many cleanings and using an optional dry-charger sock keeps it extra clean when i'm ripping through rain, dirt or mud. The forward design keeps the filter ahead of the hot air blowing off the motor, and we all know cooler air makes more power. The install was very smooth with everything fitting up perfectly to the OEM mounting holes. If you buy this intake for your Sportster you won't be disappointed.

Best Performance Intake I ever owned. My Harley XL883L kicks ass with this new setup. Thanks everyone at K&N for the best products.
