O2 sensor for S52-OBD1

[funcrew]

I have an S52-OBD1 that a shop installed for me. The engine is now running so rich that it won't pass Nevada smog. I'd like to replace the O2 sensor for starters, but don't know what model is appropriate for this setup.

Please advise.

i used the stock one from my 89 325i. Part number 11 78 1 730 005. Fap99.com list it for 70 bucks.

you need one for a 93-95 e36 325is, I done know if the e30 ones will work but the price difference is like $12+ for the e36 one

I used a 13725 Bosch 4 wire sensor from a chrsyler intrepid or jeep or something. You need to splice on the BMW connector but it is the same sensor, there is a DIY on this:

It cost $40.
