This is a genuine BMW front intake manifold support, part number 11 61 1 407 066. The number stamped on the part is 11611407066; BMW's catalog files it under the short number 1407066. You will find it on our Engine shelf, under Intake manifold system. It supersedes the older number 1427353, so a part carrying that number is the same part.
It fits every E36 body style (320i, 323i, 328i and M3, 1992–1999), with the M52 or S52 engines — and the European-market versions.
BMW draws it on 3 diagrams, among them Intake manifold system (11_1492) and Intake manifold system (11_6078). It weighs about 173 g (0.4 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
