Question Need to change front o2's

Tried a search but no luck...

Need the part number for the OEM left and right front o2 sensors for a 2000 TA. I pulled them both off the car and laid them on the bench and now I have no clue what goes where.

part# AFS098
part# AFS123

I need to replace them both at the same time and add extensions. I read the sticky on them with just splicing and extending the cable but I would not recommend it to be a solid fix. It will last a while but not as long as just doing it the right way. I did save some cash but now I will have to pay to set it up correctly. I see that Texas Speed has extensions and I will always go back to them for recomending the MS4 cam (which I love)

Has any one ever tried the Delphi or NTK brand of O2 sensors. The Delphi seem to be rated close to the Ac Delco but I want to make sure its not a marketing ploy.

Last thing: what is the best length of extensions to use as I have hooker supercomp headers (thanks to Tiago)

Correct. a Bosch 13111 o2 is for a corvette but with longer cables. I just installed some, work great and then can simply wire tie the extra out of the way.

Yeah for long tubes I would say get the Bosch 13111's. Also, i think on rockauto there are corvette Denso brand as well. Just search under 98 C5.
I had to extend one of mine when I did LT's. Just spliced the wires to extend them. Haven't had any trouble codes, but I plan on going with the C5 02's here soon.

Thanks for the reply's everyone.
So the Bosch 13111 is the "Vette long wire O2 sensor" that will work in a 2000 Trans AM?

Yes they are labeled as downstream but they will work on our cars. There is also a Denso/Delphi or something that would work. You can grab the Bosch 13111's at rockauto for $50 + shipping. Or you can go over to ebay and pay $45 shipped for each. I was thinking I would buy one at autozone or Oreilly's and one online so that if one went bad I could take it back to the parts store. lol
I think that you really only need the longer 02 sensor on the drivers side for LT's. Seems like I remember not having to extend the passenger side. Might depend on where your 02 bung is at.
