Condensers are kind of generic, if it fits and the hoses attach without leaking it will work. However, the newer all aluminum ones seem to work significantly better and if there isn't a way to either attach or independently mount the auxillary fan close your A/C performance will be poor unless you're moving at a moderate speed. I don't think they deal with E-12's much but you might try Bimmerworld, short of the do it yourself junkyards they seem to be the cheapest. Mike W.
