Customer Feedback

I put K&N filters in my motorcycles, SUZUKI , DRZ400 2000, Cagiva Navigator 1000cc, and Honda MINITRAI, 1968, AND GOT EXTRA POWER, IMMEDIATLY, I'M VERY HAPPY !!!

The day after ordering the replacement air filter I looked down our long driveway seeing a small box. When I brought the box into the house opened it I saw a smaller box inside with K & N picture on the smaller box. Wow That delivery was almost too quick The installation was also very quick. What took the most time was walking to my tool box and grabbing a screw driver to fasten the filter. After 5 minutes of installing the new K & N replacement air filter. I started up the Suzuki Dual Sport 650 took it for a spin noticing the bike had more power and was running better. Thank You K & N. No other company on Earth can design & manufactures air filters that compare with your products.
