I installed the RF-1020 on my new (at the time) 2005 F-350 Harley Davidson Edition with the 6.0 diesel. The fuel mileage went up by 1.5 miles per gallon after installing the kit. Now with 352,500 miles on the truck it averages 19 MPG on the highway and still has the original RF-1020 on it. I clean and oil the filter regularly and I expect it to last forever. The chrome cover fell off the filter almost immediately but that didn't seem to make difference in performance. Thank you for a great product!

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.
