Piston – BMW diagram

Callout 22 on BMW’s drawing “Engine block”. Open the drawing →

Piston — a genuine BMW part, number 11 42 1 271 320. You will find it under Engine (Oil filter and lines). It supersedes the older number 11 41 1 250 420, so a part carrying that number is the same part.

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

BMW draws it on 57 drawings, among them two Engine block drawings. It weighs about 10 g (under 0.1 lb).

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