I have always been a fan of K&N filters, I had a Ram air on my last car, I purchased a brand new car at the beginning of the year and within a few months I purchased a filter from K&N. I think they do add a lil more power and a few extra mpgs. Best part, you don't have to replace them, ever, clean and go.

The best air filter I've used. All of my vehicles have a K&N air filter installed. It's very dusty where I live, many dirt roads and the cleanable K&N filter saves me a ton of money over traditional air filters.

Excellent product, every car I own has a K&N drop in filter or a cold air intake on it for one reason, quality. More throttle response was first thing I noticed and more passing power on the Hwy. MPG has improved 1-2 mpg, and I never have to replace it, just clean it when it's dirty. Thanks again K&N, you have developed me into a life long customer.
