Hey guys,

I've done extensive searching on the boards about installing a heated 3 wire O2 sensor, to replace my 1 wire. I have headers, and its no wonder i can't get into Closed loop while idling! So I've decided it's best to purchase the AFS-74 #25312179 o2 sensor from AC-Delco. I know there are Bosch equivalents, but I want to try an get the AC.

The only problem is, I can't seem to find any through local retailers! I've called autozone, advance, napa, lee autos, oreillys, pep boys, carquest. None of these places carry ac-delco o2 sensors and they can't even order them! All they carry is ngk, delphi, and bosch ones.

Can anyone recommend me some online or physical stores that carry official delco parts?

 

There are no GM Dealers near you?

 

lol good idea, ill make sure to call them up as well. I figured I might be able to get some parts a bit cheaper through a retailer, but i guess not

Goto part number search.. they have it.

 

When I ordered AFS-74 lambda sensor from Rockauto few years ago ,at sensor reads Japan(maybe Denso made sensor???)

 

Yea, I did the rockauto search as well but I read that its probably denso, and not delco anymore.

 

I don't think Delco makes anything anymore...


I just picked up a set of copper AC plugs and they are the same as autolites. Same plug from china. Different printing on the side.
