I have been looking for a Aftermarket air filter for a 2.7t and I have been unable to find one. The airbox has been driving me crazy. Let me know if you have a good web page to buy this from and other audi parts. Thanks.

I put a K&N panel filter in mine. I think they may also do an induction kit for it or the S4 (same engine) Mine was a big improvement over a dirty stock filter.

 

Yeah I already actually have that I'm looking for more induction but I will check it for S4's. Thanks

You probably don't want hear it, but the stock airbox is pretty unrestrictive...unless you're going for the sound.
