This is a genuine BMW idling system, part number 13 71 8 523 475. The number stamped on the part is 13718523475; BMW's catalog files it under the short number 8523475. You will find it on our Air Intake shelf, under Intake silencer. It supersedes the older number 7705442, so a part carrying that number is the same part.

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

BMW draws it on the Idle-speed control system (13_1302) diagram. It weighs about 170 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.
