The first one I bought for my truck lasted 15 years. Well worth the money and helps with mileage and performance.

4 stars only because of the price. I know they're worth it, just a lot all at once for a filter.

We just bought the 2012 E 350. The air filter was old and just nasty. Cleaned out the tube and the air box. Just had to get a K&N. All of our cars and my Triumph Rocket have K&N filters. Thanks for such a great product .

The K&N replacement air is exactly what I wanted for my RV. This air filter was recommended by a friend and I was not stopping until I found it. The filter fit perfectly and I had it installed in less than a minute. I have always used K&N products when applicable and have never been sorry.
