Genuine BMW part 11 12 1 725 686: Cap nut. The number stamped on the part is 11121725686; BMW's catalog files it under the short number 1725686. You will find it on our Engine shelf, under Cylinder head with cover.

It fits every E46 body style (316i, 316ti, 318i and 318ti, 2001–2004), with the N40, N42, N45 or N46 engines.

BMW draws it on the Engine acoustics (11_3197) diagram. BMW's catalog calls for two of these at each place it is fitted. It weighs about 10 g (under 0.1 lb).
