Review on Mann Filter CU 3037 Cabin Filter: Excellent Choice for Audi Models by Alexander Chavis

Perfect fit for my 2008 Audi A4 Quattro (B7). My old filter hadn't been changed in a very long time and was all black and dirty. There are no problems installing this brand. I checked out a few local auto parts stores and the cabin microfilters for my Audi are between $25-$40. Too expensive compared to this one on Revain. I would definitely recommend this filter to all Audi B7 owners and the replacement was very easy. I know for sure that by ordering this filter and installing it myself I saved some money compared to going to the dealer. Prime shipping was fast as always so everything was done quickly.
