Genuine BMW part 11 25 7 512 528: Mahle piston. You will find it under Engine (Piston with rings and pin). It supersedes the older number 11 25 7 509 177, so a part carrying that number is the same part.

BMW draws it on 2 drawings, among them two Crankshaft-Pistons drawings. BMW's catalog calls for six of these at each place it is fitted. It weighs about 406 g (0.9 lb).
