What's Included

O-ring — a genuine BMW part, number 17 21 1 742 635. The number stamped on the part is 17211742635; BMW's catalog files it under the short number 1742635. You will find it on our Cooling System shelf, under Oil cooler. It supersedes the older number 1712353, so a part carrying that number is the same part.

It fits the E36 sedan, coupe and convertible (318i, 320i, 325i and M3, 1992–1999), with the M40, M50 or S50 engines — and the European-market versions.

BMW draws it on 31 diagrams, among them Throttle housing Assy (13_1726) and Transmission Oil Cooling (17_0088). It weighs about 1 g (under 0.1 lb). It also comes in BMW kits Gasket set cylinder head asbestos free (1402384) and Gasket set cylinder head asbestos free (1405282) and 2 more.

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