 Great product and service.
Kevin Bunch, Tampa, Florida
 Excellent quality as expected with any K&N filter. It was a pleasant surprise to see the O-rings were thicker than the OEM filter maybe it won't leak now.

 This is not the first time I have ordered parts from K&N. I am always happy with the delivery and quality of the product. Thank you and keep up the good work.
