oh and FYI....most members on here are going to tell you get KW coils. how soon are you looking??? I'm looking at taking my ksports off pretty soon. But IDK if they will fit the e90. I put them on 08/18/12 @ 60k and I have 64ishK on the dash now. I'm thinking about getting air...so if I get air I will no longer need the coils.
too much to list...just know its wide and low
