Customer Feedback

THE K&N AIR FILTER THAT I ORDERED WAS SHIPPED OUT AND RECEIVED IN A TIMELY MATTER. I WOULD RECOMMEND IT TO ANYONE LOOKING TO UPGRADE FROM THEIR STOCK FILTER TO A HIGH PERFORMANCE FILTER. AWESOME FILTER!! THIS WILL GO ON MY 2013 HARLEY DAVIDSON STREETGLIDE.

Fast delivery. Chrome finish is a plus. The external socket fitting will make an easy removal on my next oil change. I trust the engineering K & N designs into their products to filter out contaminates to protect my 2006 Harley Davidson 35th Anniversary superglide motorcycle.

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.
