What's Included

Expanding nut — a genuine BMW part, number 63 12 8 374 670. The number stamped on the part is 63128374670; BMW's catalog files it under the short number 8374670. You will find it on our Lighting shelf, under Headlight.

It fits every E46 body style (320i, 323i and 325i, 1999–2006), with the M52, M54 or M56 engines — and the European-market versions.

BMW draws it on 39 diagrams, among them Single components for headlight (63_0472) and Single parts, xenon headlight (63_0550). BMW's catalog calls for four of these at each place it is fitted. It also comes in BMW kit Set of mounting parts for expansion tank (0152375).

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