O-ring — a genuine BMW part, number 12 14 1 748 398. The number stamped on the part is 12141748398; BMW's catalog files it under the short number 1748398. You will find it on our Electrical shelf, under Other Engine Electrical System parts. It supersedes the older number 0148893, so a part carrying that number is the same part.

It fits every E36 body style (318i, 318ti, 320i, 323i, 325i, 328i and M3, 1992–1999), with the M44, M50, M52, S50 or S52 engines — and the European-market versions. It also fits every E46 body style (316i, 316i 1.6, 316i 1.9, 316ti and 318i, 1997–2004), with the M43, N40, N42, N45 or N46 engines.

BMW draws it on 77 diagrams, among them Cylinder head attached parts (11_1281) and Cylinder head Vanos (11_1282). It also comes in BMW kits Gasket set cylinder head asbestos free (0004553) and Set Mounting Parts Short Engine (0007008) and 58 more.

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
