I have an 07 335 e90, and I have seen atleast two different part numbers for the OEM plugs. One is BOSCH - 0242236510 / FR7NPP332 , and the other is ZGR6STE2. I did a search, but found nothing set in stone. Should the coils be replaced at the same time?

My understanding of the part numbers:

Bosch Plugs for N54:
OEM: 12 12 0 037 244
Bosch: 0 242 140 507 / ZGR6STE2

Bosch Coils for N54
OEM: 12 13 7 594 937
Bosch: 0 221 504 470

I ordered both the BMW OEM coils and the Bosch coils to determine the difference. Only difference was the box, part numbers on the actual coil were identical.

I did further research, and everywhere I looked, ZGR6STE2 came up, and was supposed to be OEM.

Just did my plugs and I used Bosch ZGR6STE2. Went super smooth and handled Stg 2 tune w/o issues.
