This is a genuine BMW clamp upper, part number 18 30 1 433 550. The number stamped on the part is 18301433550; BMW's catalog files it under the short number 1433550. You will find it on our Exhaust shelf, under Suspension parts exhaust.

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

BMW draws it on 3 diagrams, among them Catalytic converter/front silencer (18_0242) and Catalyst/Lambda Probe (18_0253). It weighs about 100 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.
