My third K&N filter, this one for my wife's Audi allroad. She noticed the difference right away.

I drive my 2005 VW Passat 1.8 all over the Midwest for work. My average highway mpg increased well over 10. Before, I was lucky to average 27 mpg at 70 mph. After replacing old paper filter with the K&N, I've easily reached an average of 30 mpg, even in cold weather. Very impressed.

I received the filter in about 4 days under normal ground shipping, I installed in 5 minutes and the car really goes at the low end. The toy car will be donated to Marine's Christmas toys for tots. Thanks, Glenn

Great product, fast well packaged delivery, which was included in the price. Perfect fit for my Bmw 540 and I can feel the difference, not massive but there is only a limit on how much it can improve - acceleration is just that little bit sharper. Would definatly buy another one when required.

I got this for my 2006 Audi S4, and it's a perfect fit. For those that are wondering / hearing that the K&N filter doesn't fit in the stock air box on the B7 S4, it does indeed fit, but it helps if you install it in a certain way. I tried dropping it in top first and pushing the bottom edge in, but I couldn't make it fit. But when I tried the other way - inserting the bottom first and then squeezing in the top edge, it was much easier. The top edge of the box must have more flex or something. Considering how difficult it is to replace the filter, and how little room there is to work around the engine, I am thrilled that I can leave the K&N filter in there for 50k miles if I want. Well, maybe I'll check at 30k. I recently went out and purchased K&N for all my other vehicles.
