This is a genuine BMW valve Seat Ring Exhaust, part number 11 12 1 435 923. The number stamped on the part is 11121435923; BMW's catalog files it under the short number 1435923. You will find it on our Engine shelf, under Cylinder head with cover. BMW has since replaced it with 1435924.

It fits every E36 body style (318i, 318ti, 323i, 325i, 328i and M3, 1992–1999), with the M42, M44, M50, M52, S50 or S52 engines — and the European-market versions. It also fits the E46 sedan, coupe, convertible and touring (323i and 325i, 1999–2006), with the M52, M54 or M56 engines — and the European-market versions.

BMW draws it on 10 diagrams, among them Cylinder head (11_1504) and Cylinder head (11_1506). It weighs about 10 g (under 0.1 lb).

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