Since installing the K&N intake system on my 2003 Harley Davidson Fat Boy, I have noticed considerable increase in power. My Harley is the 2003 100 Year Anniversary edition and I have several anniversary parts on it, including the breather cover. With this K&N kit, I was able to maintain the use of all specialty features. The kit was very easy to install. I had it completely installed in less than 30 minutes. Thanks again and I look forward to doing more business with you in the future.

The technician at K&N was very quick to respond to my query and gave me excellent detailed specifications to fit an air filter to my old Harley Davidson 3 wheel golf cart. The original was lost and this filter fit perfect and performs very well and looks much better than the original. I also run K&N on my Ford Expedition.

Great product. I use it on all of my motorcycles, and have never had an issue. The gasket on this unit was pretty thin rubber, and when I recharged the unit last, I had to replace it with a Harley Davidson gasket.
