Always a great product! It improved my mileage a little bit, added noticeable power and it sounds awesome.

K&N, enough said.

I've always had great luck with K&N filters. Unfortunately three days after installing this filter I was involved in a hit & run. The vehicle was totaled. Also had just installed 4 new [brand] tires. Too bad but that's the way life rolls. Will more than likely install one in my next vehicle.
