K&N has always been and remains to be a superior product, always a perfect fit. I have put these in 7 different cars now, no issues no fitment problems. I am loyal to the brand and refer them :) Cheers

I love K&N Air Filters. I use them all the time...excellent increase in horsepower (engine responsiveness) and gas mileage. I was just concerned with the pricing on the K&N Home website, it's very expensive compared to another website I had found. Still a great product though.

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.
