This is a genuine BMW T-Connector, part number 11 72 1 439 973. The number stamped on the part is 11721439973; BMW's catalog files it under the short number 1439973. You will find it on our Engine shelf, under Secondary air system.

It fits the E36 sedan, coupe, convertible and compact (318i, 318ti, 323i, 328i and M3, 1992–1999), with the M44, M52 or S52 engines — and the European-market versions. It also fits the E46 sedan, coupe and touring (316i, 316i 1.6, 316i 1.9 and 318i, 1997–2001), with the M43 engine.

BMW draws it on 53 diagrams, among them Air Pump F Vacuum Control (11_2071) and Air Pump F Vacuum Control (11_6092).

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