Hello guys,
i use BMW 435i FBO, meth, etc on pump gas
I just installed S55 spark plug and it seems my car wont boost and it holds at 11psi, does it effect on the gap or etc?

Hey,
What gap did you put on the plugs?
Do you have any logs of the issue + a photo of the users adjustment settings would be nice.

PS: m2's use the s55 plugs w/o issues.

I ran them fine on my N55 with FBO and now with just MPPK and JB4 they still work fine. Stock gap, whatever it may be.
