I replaced the new Busch spark plugs I had just installed for NGK part# 97506 gaped to .030".
What year M5 has your friend?
Maybe I can see if the Delphi will work and exchange the Eldors for Delphi.

He has a 2012 but it should be all the same coil design from 2010-2016. I know others on here have used the Eldors just fine on even newer F10 M5's, I am wondering if they sent you the right coils? Can you post a pic of one of the Eldors?
Just double checked: All F10 M5's from 2011-2016 use same coil design so something is up with the Eldors they sent you, post a pic when you can and model number stamped on side.
