Review on Mann-Filter CUK 8430 Cabin Filter with Activated Charcoal: Ideal for BMW Models by Christopher Penn

Great OEM replacement for BMW 3 Series (2006-2011) filters. Don't be fooled by a BMW dealership who will charge you $80 for the part and labor, order it and do it yourself. There are tons of videos on Youtube explaining how to do this if you don't is mechanical. Took 8-10 minutes to install and it fitted my 2008 335xi perfectly. The slightly "musty" smell that appeared at higher air conditioning settings has been completely eliminated. I recommend cleaning the filter housing with an all-purpose cleaner before screwing in a new one, especially if you haven't changed your filter for a long time.
