Bosch plugs gave my Z4M a rough idle , I had them in there for 1000kms (fitted March 2020) and then changed them back to the OEM ones 3 weeks ago, all good again. That’s my experience with it.

OEM NGK.

The spark plugs last a long time on these engines, so I would just use the right stuff from the get go.

NGK only. Don't go with Bosh, they run cooler and mess with fuel consumption and lumpy idle.
