I had the apollo fmic installed on my car (by kaz(vabch) and It doen't fit very well, instructions suck. It isn't a very good choice if you have stock turbos ( I do). Would I buy the apollo again? NO. Would I spend more money and buy a better FMIC? YES IMHO I like the way they look and in the future it will actually be necessary. (not that upgraded SMIC's wouldn't do the job)
