On realoem, for my 330i at least, it says that the Bosch ones were discontinued. Delphi are now the OEM suppliers of coils.

Deffo worth going with genuine Delphi. These coils have been through several iterations, so buying from a BMW dealer ensures you have the latest version...

I bought six from ecp when two of mine failed in succession just after my remap, they were Bosch & only £20 or so each, they've been on the car for over three years & are still fine.

I bought plugs and coils from ECP on a deal and they were cheap as chips. Mine were totally knackered by oil and the plugs looked like they had been in since new. It's like a new car!

Nothing wrong with Bosch or Delphi, BMW are only using Delphi because they are cheaper.
