Hey, there is a guy selling supposedly AC Delco o2 sensors and he is listing the part # as AFS105. I tried searching that part # on here and got nothing. Can anyone verify that these are in fact genuine AC Delco o2 sensors. I need some new (front) o2's for my build. Thanks for the help.

They are genuine AC Delco's but I am not sure if they are the right ones for your application.

Here's what I have:

1996-1997 front heated oxygen sensor
AC-Delco # AFS75
GM 25312184

1996-1997 rear heated oxygen sensor
AC-Delco # AFS97
GM 25312196

Hmmm, all he said is that it was for a LT1 bird...

They may be...I have bought two fronts in the past year with different part numbers than I just mentioned. I will not be home for a couple weeks otherwise I'd check for you but its possible thats the same part # as what I have. I do know however that the part# you gave are for a flat four pin connection which is correct.

I have a set of basically brand new afs75 delco o2's. They had enough run time to on them to determine that my bosch units worked fine! I will sell both to ya for 100.00 shipped!

Damn, thats a good deal if they will work. I paid 60 a piece for the afs75's 2 months ago. No biggie, I will just keep them as back up before I let them go at that price.

Ac Delco lists the afs75 and afs97, really not sure on that afs105

You need AFS75 for front! I have a 97 and I went thru 2 sets this summer!

Is the rear O2 sensor the ones with the square connector?
