Bosch Classics would have a listing or remove the old one for a part number.

20,000 would I assume be 1987 or newer but it would help if you provide the exact year and model.
My parts vendor shows Bosch 13047 which interchanges with the early E30 BMW 318i (not the m40/m42 engine).

Thank you.
Car is a 07/1988 built Corniche II # 24509.
On the car, sensor has the small, 3 connectors, round plug :




Bosch 13047 seems to be in short supply.
Found this page :



Looking through the compatible Denso # , this Bosch part surfaced :


Looks very similar, to me.

This one appears to cross reference to an E30 BMW M3 so I expect that it will add at least 50hp if you use it instead of 13047 which is for the E30 318i.

Hello,

Part NumberUE70368
Chassis Range ApplicabilityFrom VIN 23935 to 40000
This sensor cross-references to the Bosch global part # 0258003016

0258003058 can be used, the only difference is the length of the wire.

I would assume that the 058 is longer, but, I would check with the vendor prior to purchase.

There are a few other part numbers that can be substituted and the only difference is wire length.
