BMC FB573/08 Performance Air Filter for Audi A6 C6 (2004-11)

Using it on a Audi A6 C6, the fit feels sealed and snug after the swap, and the filter media has become properly engineered, it is a good product.

After a chilly morning ride, the mid range is plainly more alive, it is a great feeling, the performance is better now.

The construction reads a clear step up from stock and the airbox fit is honestly clean with no trimming and the induction sound proved subtly better, overall it is a good buy.

With my Audi A6 C6, the construction is now dense and well made, the intake note is nicer and meatier and then some, and throttle pickup is easily noticeably crisper, being washable ended up a real long term saving.

Late night riding, the fit is plainly faultless, and mid range pull stays cleaner now, it is a big plus, I like the product.

For the Audi A6 C6, the mid range ended up stronger, and the build has become a clear step up from stock, pickup has proven cleaner off the bottom so far, my only gripe, keep it clean and it keeps performing, that is the key.
