I was calling around for an AC Delco and the "NAPA" store guy tells me that Bosch makes O2 sensors for AC Delco and that most Delco boxes I open will have a Bosch made O2 sensor inside. Is he full of it?

Kind of put me off buying one for now. Maybe purchase through GMPartsdirect.com ??

He is in fact full of it. If anything, Denso would make AC Delco O2 sensors, as NGK (Denso) makes Spark plugs for AC Delco.

I did see a Denso o2 sensor, but shyed away from it because of the stupid sounding name.

why are bosch O2'* bad? i know their spark plugs don't belong in our engines, but why not the O2 sensors?

not saying i'm gonna buy one, i'm just curious

This one in Rockauto is $72.00

the AC delco is like $45 bucks tho, and it'* OEM, and recommended by the gearheads (not saying all, but for the most part)

it was an AC Delco

Here'* a new AC Delco AFS109 front o2 sensor for $45.00 + $5 shipping on ebay.
Save some money.

I heard the same thing frm the Napa shop here. He says AC Delco hasn"t made parts in quite a while> It will say AC Delco on the box, but Denso on the inside.
I haven't found an AC Delco o2 sensor anywhere. I doubt that one on ebay is actually an AC Delco.
Is there a member here that has one that they can sell me??
