Thread: Upstream O2 - Brands..

So, I need an upstream O2 on my '99 GTP and was told to get an AcDelco, problem is I can only get one online for $30 and it'll take a couple weeks, or at the local GM Dealer for /$86/.

When calling up the four local parts stores they all had Bosch (lowest for $53) and/or Denso (lowest for $46). Wondering if I have to get an AcDelco, or if Denso is okay?

Thanks

Denso is fine...stay away from bosch

Okay, thanks!

acdelco only in my world.

AC Delco really doesn't make anything themselves. Delphi and delco were two different companies that became part of GM. They are just under the name AC delco. Both delphi and denso makes parts for GM and other car makers. And most of the stuff does come from mexico and china now. To me buying a AC delco branded o2 sensor would be the same as buying a denso o2 sensor.
