Fast service and shipping, it was easy to find the correct filter and it fits perfect. I will recommend to family and friends.

Part was exactly what I wanted and came in a timely manner. The difference in performance between the standard filter and the K&N filter is noticeable.

Great air filter... just a costly investment... the price is the only thing I don't like about it. It works well on my early 90s Yamaha Timberwolf 250
