K&N’s Street Metal™ Series High-Flow Air Intake Systems provide a good looking appearance, offer increased airflow and deliver more horsepower & torque to your Harley-Davidson® motorcycle. These intake systems increase power by eliminating the stock OE air cleaner and replacing it with a complete High-Flow Air Intake System. The sturdy, custom aluminum backing plate mounts directly to the throttle body via an aluminum integrated, internal-run breather system. The intake system comes with a K&N Air Filter for high air flow and long service intervals. A durable mounting gasket is also included to help absorb vibration. The K&N High-Flow Air Filter™ is washable, reusable, pre-oiled and ready for installation. Simple designed custom covers give this air intake good looks while powering down the highway or at your local show.

  Best air intake system I have found. Even better than the hyper charger I had before. This is the 3rd review that I have done and I dont know why you wont post this .I do wish you guys would sell the replacement filter alitte bit cheaper.

  For the price I like this air intake. I even like it better then the Hyper Charger I had on my old bike. I would tell everybody that this air intake is the way to go. You guys make good stuff. It would be nice if you came down on the price of the replacement filter but hey, I even have K&N filters on my suv. I won't use anything but your filters.

  For the money I couldnt have gotten anything better. I like this air cleaner better than the [brand] that I had.

  This filter works great! I could hear and feel the difference from the first start up. Better throttle response and gas mileage.

  Best value I found on a great looking intake. Classic, clean, and well engineered. Also get the quality and reliability that comes with K&N products. Thanks for recognizing the need to build a quality piece around your filter. Originally bought it to save money and decorate with a medallion. Once I opened the box... I knew it was going on as shipped. Reasonably priced. Exactly what I would expect from K&N. As far as the filter? There is no other filter!
