Where is the best place to get a heated O2 sensor for a good price. Anyone have a part number that I can take to Azone, Checker, Napa, CarQuest, etc? Its for a TPI application. Thanks

I got one a few weeks ago from pick your part from a 90 something chysler mini van this one is a four wire, some are three wire. I'm going to try this one out first before I buy a new.
 
I believe you'll find the recommended part number over on thirdgen.org, and I'm 99% sure that it's going to be delco.
 
It is for EFI applications that can't have an o2 sensor close enough to the exhaust manifold to get accurate readings. For instance trucks with headers. THe o2 sensor gets put into the collector but at that point in the exhaust system the collector is not hot enough and won't give accurate readings because the sensor is not hot enough.

The heated o2 is connected to a battery source to heat it up and get more accurate readings.

I believe the Delco heated one is off the corvette!! I know that the heated vette units fit the LS1. They are heated to keep from having to clean them all the time when running headers and the mixture is a bit off.

Harley,

I have a 4-wire heated O2 sitting in the garage hopefully going on the truck today (after the girlfriend gets her ride to the doctor) I searched an O2 by application an the one I have is for a 1997 Vortec 350. Then I went to GM and bought teh bactory pigtail harness so I could have a factory weather-pak plug. Then Wade hooked me up with the wiring diagram. It's pretty simple: 2 grounds, a 12V+ ignition and the sender wire to the ECM.
