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. :confused:

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)

All 4 are exactly the same.

Use Corvette O2s and you wnt need extensions.

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.

Imo extentions are no good i had 3 sets and none of them locked out moisture keep on getting misfires went with the vette o2 and no problems since

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.

I got mine on amazon.com for $32 each.
shit, they're down to $29.99 ea!
