I decided to save the $200 the dealer wanted to replace the cabin air filters on my M550i (which BMW makes amazingly more difficult to change than other makes I own).. But in making the switch, I pulled the old ones out without noting the airflow direction, and I can't find arrows on the vehicle or online denoting the direction. I did read that in general, the airflow goes from the engine bay into the car, which would make sense, but I have no confirmation that's the case in my vehicle, or if the airflow direction is changed with the duct configuration. A few youtube videos suggest that the arrow should point to the FRONT of the car (seeming backwards to me?) Any ideas?
