As an advocater of a lot of the chinese stuff for our cars, I want to point out and advise to avoid fake spark plugs that are starting to appear, and if you buy on eBay, be careful.
The fakes have darker tips and a more chrome looking body. They're also imprinted BMW NGK.
A mate in the uk had these and the tips cracked up into his engine scoring up the bores of his newly built block.
These are fake 97506 (2 steps colder).
Images attached of fakes, and (probably) genuine.
