Customer Feedback

It's the best air filter. I use this filter (RU-4740) on my Honda TRX450r for many years, great quality. Thanks

Very efficient filter. Good instructions both online and enclosed with the packaging. Simple straight forward replacement for my old filter. My car is a 2013 Honda Fit Sport and the exchange took less than 5 minutes to accomplish. I also have a cool air kit with the K&N ait filter and it works great! Thanks - Keep up the good work.

I have a 2014 Honda Accord LX, and was kinda interested in purchasing an intake system for it. Looked it up at KNFilters.com and found it was a great product. Ordered it right away. The Intake was installed and is the greatest invention ever made! Delivered Friday, installed Saturday. Thanks for the quick shipping on that.
