Product Reviews

  Great product. Have used K&N filters in my other vehicles and have been very happy. The on-line purchase is easier than trying to find the correct product in a brick and mortar site.
Neal Morgan La Verne, California
  The filter is superior over the stock one.

  Quick, easy and convenient. Competitive/comparable pricing. Free shipping. Fast shipping.

  I am fully satisfied with my K&N air filter. The combustion of the engine, I think, is much better. The exhaust sound is much rawer, so is the torque, much rawer, higher. I don't know if the consumption of gas will decrease ... because the fun of riding is so much increased. My bike asks now to have fun ... and that's what my wife and I are doing ... have fun.

  Good fit. Good performance. Good price. Delivery as requested. I have not used the recharge kit yet but will be giving feedback when I use the kit. I suspect it will be exactly as advertised.
