Great product, perfect fit. I have them on all my vehicles.

Put in a new K&N air filter and it's like driving a different car. I put one in my '03 PT Cruiser GT turbo and that little car turned into a butt kickin' street machine. Believe it or not, that little car is faster than my 1993 Mustang LX 5.0 convertible (with a K&N in it, too) on acceleration. Plus, it gets 23 mpg (up 2.5). I put a K&N in my '02 Indian (S&S 88 c.i.) and it was like riding a different bike, and those long shot pipes sound so much better! I have K&N in all of my vehicles and you can't go wrong with them. Better performance and fuel mileage all around. Plus you never have to spend $10-$15 on the disposable paper filter every 10,000 miles. K&N is a win-win situation any way you look at it.
