As long as the Bosch ones match the factory specs then I’m sure they are fine as many other parts and sensors on these cars are made by Bosch.
Pros: match factory specs

Im tuned and on an E85 mix but using 1 step colder NGK's (#ILZKBR7B8DG) gapped to about 0.022...needed these before I even went MHD though. Once I did most of my maintenance, the car required this for proper spark. Night and day of a difference.
Pros: proper spark, night and day
Vehicle:
BMW
Part number: ILZKBR7B8DG
NGK and Bosch are the same ones as the Genuine BMW ones. The latter are just rebranded and marked up.

Don't use autolights. AC Delco for GMs & Motorcraft for Fords. Modern ignition systems are sensitive to plugs so I use whatever the OEM does (within reason)
Pros: AC Delco for GMs
Cons: Don't use autolights
Auto lights are trash, Bosch too. I can’t tell you how many times I get a misfire diag that the customer already put plugs in, only to find the garbage auto lights are the issue. A set of oem plugs always fixes it
Pros: OEM plugs always fixes
Cons: Auto lights are trash
