I think i remember reading in previous threads that the BMWs have very efficient ignition systems, and that there isn't really a need for aftermarkets. Anyway, thats what I';ve read. Also, you don't see this as a common mod, if at all ,which supports the notion that you don't need it. Maybe if you're track racing or something...
Example: Dinan doesn't modify via an ignition system. INstead it's about chipping and changing software. That chevy prolly has a distributor, which e36's don't have--I don't think--maybe the 318's.
Spend your money on better mods IMO.
