I had an awesome experience. There were no problems with my order and my part was shipped directly to me in a timely manner. It was the right part and I can tell the difference in my arc. Thanks K&N, I look forward to doing business again.

I have a 2001 Yamaha Grizzly 660 4x4. I switched out the stock air filter that was falling apart and replaced with KN filter. Good fit, easy to install and should be a great addition to the quad.

Couldn't be happier with the fit, function and performance gain. Having the piece of mind that I have the best filter on the market protecting my quad while I'm racing all out, it's well worth the investment. It's a must have if you jet your carb and run a full exhaust system!!!
