Lambda-probe bracket — a genuine BMW part, number 12 52 1 734 181. The number stamped on the part is 12521734181; BMW's catalog files it under the short number 1734181. You will find it on our Electrical shelf, under Other Engine Electrical System parts.

It fits every E36 body style (318i and 318ti, 1992–1999), with the M40, M42 or M43 engines — and the European-market versions.

BMW draws it on 2 diagrams, among them Catalyst/Lambda Probe (18_0227) and Gearbox parts - lambda probe holder (23_1281). It weighs about 29 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.
