BMW itself have upgraded their coils parts multiple times...
BMW switched from Bosch to Delphi coils and then later again to Eldor branded coils.. each time quality, coil weight went up...
BMW parts catalogue lists Eldor as the most current replacement part...

Price difference between them is small so get the latest that is available to you.
My car is running Delphi coils...

Stock Bosch sparkplug is around 10 eur a piece... iridium stuff costs more... but thats for tuned cars.. with them you get into 1 or 2 step colder plugs.. and they have to be gapped aswell...

Also did i really read it right? over 300K km on the odometer? this must be one of the highest mileage e89-s out there doesnt it?
