FMN Piston — a genuine BMW part, number 11 25 7 799 357. The number stamped on the part is 11257799357; BMW's catalog files it under the short number 7799357. You will find it on our Engine shelf, under Piston with rings and pin. It supersedes the older number 7790702, so a part carrying that number is the same part.

It fits every E46 body style (320d, 320td and 330d, 2001–2005), with the M47N or M57N engines.

BMW draws it on 2 diagrams, among them Crankshaft-Pistons (11_2097) and Crankshaft-Pistons (11_2321). It weighs about 950 g (2.1 lb).

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