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.
