Sorry Numark318i, I mistaked you and the other guy with a red 1991 e30 318 (He goes to Michigan I think). His name is escaping me.
Don't buy a filter from Napa auto. The filters there are typically junk, especially the fram filters. Buy one from the dealership with a BMWCCA discount and it won't be too much. In the future just order 5 and save on shipping from bavauto or wherever you want. Just get the OEM Filter.
