"My recent purchase of a K&N Air Filter is for a new vehicle that I recently purchased. I had had K&N Air Filters in the previous two vehicles that I had owned and I knew from first hand experience that I wanted one in my new SUV too. They are great and do just what they say they do. The one time purchase price more than makes up for the cost of having to replace a "regular" air filter every 5,000 miles. The K&N boots horsepower and increases gas mileage. Which with the price of gas these days, is a very useful thing.
I have reccommended K&N Air Filters to my friends and several of them have purchased them for their vehicles and have been very pleased with them also. I highly reccommend them for anyone who wants the "best" for their vehicle!!!!!" —Gary W from Lubbock , TX bought a K&N Air Filters for a 1998 BMW 3-Series.
