I'm very happy with the K&N air filter. Don't think about getting one installed, just do it. My bike response is great on the throttle. I'm very happy . Customer service is great. Thanks K&N.

I have used K&N filters for all of my Harley Davidson applications. I just replaced the HD filter with this and am pleased as usual.
