Product Reviews

  I needed to meet some very specific criteria to refit my twin turbo RX-7 set up. Your charts are very detailed, and show a multitude of critical dimensions. Very useful and helpful to me. Even though my selection was out of stock when ordered, you delivered my units within a very reasonable time. Over the years I have used K&N products for many applications, street and track. There is NO substitute for your fine products.

  I self designed a new intake for an older bike I have to do away with the flat panel filter it had . I located this filter on the web site and the rest was history ! No more leaky flat panel filter and now big time air flow with no restrictions, to say the least I'm extremely happy with it's fit and performance.
