The filter does make a difference in my gas mileage and in performance. It is a small difference but it all adds up in the long run. Better than the stock filter, you can see that just by looking at it.

I've been using K&N air filters since back in 1995 for my first car and I've had to order a couple for my car since then. Never let me down and you can tell right away when you put it in. It has a faster pick up and good air flow.
