In general you can trust, including but NOT limited to:

Mahle, (Victor) Reinz, Continental, Mann, Siemens VDO, Bosch, Delphi, Corteco. Meyle?

Definitely a few others, but these are the companies that make like... 3/4 of the car. Multiple companies may supply BMW the same part, depending on year, revision, availability in that moment, contracts, quality or mean-time-to-failure/statistical analytics, etc. a million things can affect it.
