AC Delco heated O2 sensors

[Nick Micale]

These are original AC Delco, 4-wire, AFS-109 O2 sensors made in the USA.

I have 4 of them at $25 each.

Make a reasonable offer on all 4 and will consider.

Adapter harness needed for this O2 sensor

I have no experience with those. Benefits? How do you connect them?

Thanks for asking Irv, the heater O2 sensor is a 4 wire connection, not the single one like stock.

A one time, maybe still, Casper's made a plug-and-play adapter harness so no cutting or any mods were needed.

Since you have pointed this out, I want any potential buyer to know this.

Going through my "pile" of old stuff, I do have one new adapter harness.

I will honor the requests for purchase as they are in line here, but I want to be sure all potential buyers know about the need for an adapter harness before hand.

Nick what's the price with the harness? Put me 1st. Thanks.

I am sorry guys, captflash was first in line and he had said he will take the package.

Thanks for your interest and stay tuned as I clear out my stock of other 20+ year old turbo Buick parts.

If your running 116oct fuel it want burn out your 02 if your 02 is a heated one.But I have been running 110 with no issues for 6 months now

I run 93 and methanol. Whats the best O2 for me? I just replaced with a Denso like i always used. Do they normally jump higher numbers at higher rpm's than at idle?

I have not changed mine sence I bought the car. I installed ATRheaders Saturday and I pulled the old one out with by the way was a GM and put it right back in . But the numbers will bounce around , mine does. The one you got should be fine.
