I have Googled and Gaggled but simply cannot find ANY resources to improve performance of my 2004 Z4 2.2.
Short of replacing everything with an M3
I just want to have a little better performance from the engine. THEN, if I do get a nice boost I will be looking into other mods such as suspension, etc.
Yes, I really want to do this. The car is basically BRAND NEW with about 10K miles on it.
thanks to everyone in advance for any suggestions.
