Just bought a 1999 528i and am in need of new ac filters. Looking for who's got them for the best price. Where do you all buy yours? Is it worth paying more for activated charcoal? Thanks for your help.
I'm sorry. I abbreviated "air conditioner" with "ac" and confused you. I was talking about the two air conditioner filters under the hood at the rear of the engine compartment that filter the intake for the ac in the car. They are also called cabin filters.
