That part has now "Ended" and the only current part that is shown is listed under the 320 N20 configuration, part no. 11257640168. I'm assuming that 328 engines made after 11/12 is made with the new piston/engine configuration using the same pistons in the 320.
That said, I could be wrong and possibly someone who works at BMW could confirm part numbers.

That makes me nervous.
It means either the 320 is getting better pistons thanks to the 328 or that the 328 will be getting inferior pistons now that the 320 is being made for the us and in a larger scale.
