Hi all my name is mac I have a z4 2.5 se on a 54 plate in grey very nice motor all original as far as I know which is not much lol.I've just joined this forum to see if I can gain some info on my bm and any mod cons to update and upgrade performance and looks if possible. I'm not mechanical minded nor very technical but maybe with right advice will end up with a tasty motor that would be a joy to own and drive any comments would be grateful
