He said that I have the wrong plugs unless the NGK crosses to the Bosch.
and I'm still confused. I'm looking at realoem.com both #12120037663 NGK & #12122158253 was both found on a E90 LCI 2007-2011
and it says Supersedes:
12120032138 NGK (09/01/2004 - 12/15/2009) What does that mean?

to be honest, im confused and dont know what to tell u. The bosch spark plugs work. I mean, no misfires, no warning lights , no problems at all. I did not even notice any difference between those and the OEM S/P.
