The K&N products are the best you can get for your vehicles. I use the Air filter and oil filters on my cars and motorcycles and I've been using K&N products for at least 15 years.

Excellent filter. I placed in E320 Bluetec turbo. Power is great and I love 50,000 miles before re-oiling. Old filter was clogged. Filter fit is perfect and pays for itself in 2 regular filter changes.

It's a fantastic filter, I felt the a big difference as soon as I install the filter. My diesel SUV take off like a gas powered suv. The only thing I don,t like is it does not have a good instruction on how to get the filter housing out. But I go to the internet and problem solved.
