This is a genuine BMW cylinder head with bearing ledges, part number 11 12 1 703 637. The number stamped on the part is 11121703637; BMW's catalog files it under the short number 1703637. You will find it on our Engine shelf, under Cylinder head with cover. It supersedes the older number 4495268, so a part carrying that number is the same part.

It fits every E36 body style (323i, 328i and M3, 1995–1999), with the M52, S50 or S52 engines — and the European-market versions.

BMW draws it on 4 diagrams, among them Cylinder head (11_1506) and Cylinder head (11_4932). It weighs about 21 kg (47 lb).

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