Review on Mann Filter CU 3037 Cabin Filter: Excellent Choice for Audi Models by Timothy Bobbert

This filter is perfect for my 2004 Audi S4 4.2L V-8. I've never done that. It took me 2 minutes to get almost everything ready, but it took me another 3 minutes to properly install the main cover as the final assembly step. The filter came with instructions that were just images; Clarity was bad. I found it MUCH more helpful to watch a YouTube video of someone doing it. Go to YouTube and search: replace Audi A4 cabin air filter. The one I looked at was from AutoWerksofAmerica (there are others); It says this applies to the 2002-2005 B6 body and 2005-2008 B7 body. Doing this at my local dealer would have cost me about $115, so the savings are significant for a simple job that requires no tools. I suggest taking some high quality pictures BEFORE removing the first main cover so you can see if it matches the line in your photos AFTER assembly.
