All I know is after changing my filter my AC is like night and day. Before I would have to put it on Full Blast for only 1 person to be a lil comfortable now its I keep it on Auto it stays on 2 dials and it keeps the entire car cool. When I took my filter out it was like a birds nest was laying up in there. It was crazy.

SAme here man, mine was even dirtier than a nest, the car has 208,000 on it and i dont think it was ever changed, i changed it and the ac is like if i put it on 3 u feel cold in the car, i gotta keep it on 2 to keep the car cool enough and not to catch cold, haha.. do u think the ac systems are different in the 6cyl BMw's and the 4cyl BMw's
