Also shown on Crankshaft-Pistons.

This is a genuine BMW piston, part number 11 25 7 506 943. You will find it under Engine (Piston with rings and pin). It supersedes the older number 11 25 1 437 154, so a part carrying that number is the same part.

Fits E36 316i and 316i 1.6 (1993–1997), sedan, coupe, touring and compact, with the M43 engine. Also fits E46 316i and 316i 1.6 (1998–2001), sedan and coupe, with the M43 engine.

BMW draws it on 2 drawings, among them two Crankshaft-Pistons drawings. BMW's catalog calls for four of these at each place it is fitted. It weighs about 460 g (1.0 lb).

Out of stock. Request it and we will notify you when it is in stock.
