Ever since I found out about K&N Air Filters, I have tried all the products and they all appeared to be extremely high in quality and performance. I'm sold on them and won't use anything else.

Always satisfied when buying K&N products. I would like to have an air filter and fuel filter for my motorcycle, 2015 Kawasaki Vulcan 650 ABS .

My 04 mustang gt 4.6L runs both oil and fuel now. I went from the factory original to K&N. She purrs like a kitten now and throttle response is (all though not very noticeable) better. The flow IS the edge, went and bought 5 more. Should be enough for the rest of the time that I own the vehicle. K&N has earned my business and my respect.
