What's Included

O-ring — a genuine BMW part, number 11 61 1 730 725. The number stamped on the part is 11611730725; BMW's catalog files it under the short number 1730725. You will find it on our Engine shelf, under Intake manifold system. It supersedes the older number 1726475, so a part carrying that number is the same part.

It fits the E36 sedan, coupe and convertible (320i, 325i and M3, 1992–1995), with the M50 or S50 engines.

BMW draws it on 3 diagrams, among them Intake manifold system (11_0954) and Intake manifold system (11_1124). It also comes in BMW kits Gasket set cylinder head asbestos free (1730252) and Gasket set cylinder head asbestos free (1730253) and 5 more.

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