01 View BMW DiagramSee this part on the official exploded view→Piston — a genuine BMW part, number 11 25 1 437 178. The number stamped on the part is 11251437178; BMW's catalog files it under the short number 1437178. You will find it on our Engine shelf, under Piston with rings and pin. It supersedes the older number 1437083, so a part carrying that number is the same part.
It fits the E36 compact (316i 1.9, 1999), with the M43 engine. It also fits the E46 sedan, coupe and touring (316i 1.9 and 318i, 1997–2001), with the M43 engine.
BMW draws it on 3 diagrams, among them Crankshaft-Pistons (11_1336) and Crankshaft-Pistons (11_6044). BMW's catalog calls for four of these at each place it is fitted. It weighs about 426 g (0.9 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
