NOT COMPATIBLE with older E9x N52/N54!
Tilted head, shorter shank. Literally looks like it's going in crooked, because if you look carefully you can see the head is "tilted". The OEM screw is straight, with a longer shank (more thread). I don't know how this is supposed to work for anything, because it has an O-ring under the head.I'm only not going to return it because I stole the O-rings off for later. $10 for two O-rings is about right for BMW :PI can't link you to it, but RealOEM is your friend. Look up your vehicle, and make sure the part number is correct. However, things can still go wrong such as here. This part claims to be 17111712788 but it is not compatible with 11537793373 as RealOEM says.
