This is a genuine BMW intake manifold, part number 12 31 1 436 637. The number stamped on the part is 12311436637; BMW's catalog files it under the short number 1436637. You will find it on our Electrical shelf, under Alternator with motor and mounting. It supersedes the older number 1740632, so a part carrying that number is the same part.

It fits the E46 sedan, coupe, convertible and touring (320i, 323i and 328i, 1999–2005), with the M52 engine — and the European-market versions.

BMW draws it on 6 diagrams, among them Alternator Parts 140a (12_0481) and Alternator Parts 140a (12_0629). It weighs about 116 g (0.3 lb).

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