Callout 11 on BMW’s drawing “Cylinder head cover”. Open the drawing →

Cap nut — a genuine BMW part, number 11 12 7 838 078. You will find it under Engine (Cylinder head with cover). It supersedes the older number 11 12 7 830 470, so a part carrying that number is the same part.

Fits E46 M3 (2001–2006), coupe and convertible, with the S54 engine.

BMW draws it on 2 drawings, among them two Cylinder head cover drawings. BMW's catalog calls for two of these at each place it is fitted. It weighs about 20 g (under 0.1 lb).

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