Since a few people have asked what it is and what I’ve done to my JDM Z4, I figured I’d make a quick post about it.
It’s a 2005 BMW Z4 with an M54B22 engine. I’ve fitted an M50B25 intake manifold and ported the head to match, M54B25 fuel injectors, and an M54B30 throttle body. It also has a catch can in place of the CCV system.
