Oxygen sensor — a genuine BMW part, number 11 78 1 437 943. The number stamped on the part is 11781437943; BMW's catalog files it under the short number 1437943. You will find it on our Engine shelf, under Exhaust gas control systems.

It fits the E36 sedan, coupe and convertible (328i and M3, 1996–1999), with the M52 or S52 engines.

BMW draws it on 4 diagrams, among them Lambda Probe Fixings (11_1471) and Lambda Probe Fixings (11_6071). BMW's catalog calls for two of these at each place it is fitted. It weighs about 109 g (0.2 lb).

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