This is a genuine BMW connector straight, part number 34 33 1 121 721. The number stamped on the part is 34331121721; BMW's catalog files it under the short number 1121721. You will find it on our Brakes shelf, under Other Brakes parts.

It fits the E36 sedan, coupe, convertible and compact (318i, 318ti and M3, 1994–1999), with the M42, M43, M44 or S50 engines — and the European-market versions.

BMW draws it on 16 diagrams, among them Brake servo unit (34_0249) and Power brake unit depression (34_0259). It weighs about 4 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.
