Genuine BMW part 12 52 1 737 773: Flat spring contact MDK4 2.8. The number stamped on the part is 12521737773; BMW's catalog files it under the short number 1737773. You will find it on our Electrical shelf, under Other Engine Electrical System parts.

It fits every E36 body style (318i, 318ti, 320i, 323i and 325i, 1992–1999), with the M40, M42, M43, M44, M50 or M52 engines — and the European-market versions.

BMW draws it on 20 diagrams, among them Intake Manifold-Supercharg.Air Duct/Agr (11_3412) and Intake Manifold-Supercharg.Air Duct/Agr (11_3468).

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