Genuine BMW Part

Photos coming soon

This is a genuine BMW exchange primary catalytic converter, part number 18 40 7 645 237. The number stamped on the part is 18407645237; BMW's catalog files it under the short number 7645237. You will find it on our Exhaust shelf, under Other Exhaust system parts. BMW has since replaced it with 7594012.

BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.

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