AC Delco AFS75 O2 Sensors 28.64 plus shipping at Amazon
My local auto parts store wanted $92 EACH for these. I bought 4 so I'd have 2 spares. There are 11 left. It showed 15 before I bought mine, so I guess the counter DOES work!
I don't know if these could be found cheaper anywhere else but it seemed like a good price for a necessary item.
