This is a genuine BMW earth strap, part number 12 42 1 437 633. You will find it under Electrical (Other Engine Electrical System parts). It supersedes the older number 11 12 1 722 934, so a part carrying that number is the same part.

Fits E36 320i, 323i, 325i, 328i and M3 (1992–1999) with the M50, M52, S50 or S52 engines. Also fits E46 320i, 323i and 325i (1999–2006), sedan, coupe, convertible and touring, with the M52, M54 or M56 engines.

BMW draws it on 10 drawings, among them two Cylinder head cover 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.
