This is a genuine BMW piston 'AB', part number 11 25 7 721 863. The number stamped on the part is 11257721863; BMW's catalog files it under the short number 7721863. You will find it on our Engine shelf, under Piston with rings and pin.

BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.

BMW draws it on the Piston, single components (11_4202) diagram. It weighs about 570 g (1.3 lb).

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
