You need an extension when you use F-body FRONT O2 sensor. Bcuz the wire is short and cannot reach down to the new O2 sensor bung.
However, if you use Corvette REAR O2 sensor then you don't need extension. Bcuz the Vette rear O2 has longer wire, alot longer.
Therefore the FRONT and REAR here just reference to different model part/part number. There's nothing to do with the sensor location, again there's only one O2 sensor bank after header installed.

after having the same issues i discovered there are two types of ac delco sensors, the ones originally on the car had slits cut into the tip, after replacing one ,right forward i still had a code, auto zone scanner said the faulty one is the new one, so exchanged it for one that has holes punched in the tips, perhaps this one gets a better reading, the light is out for now

I am looking for a decent pair as well. From what I have read from all the online searching I have done, I would stay away from anything made by Bosch. It seems like the majority of those that are having O2 issues soon after putting new ones in are those who installed Bosch's. I just ordered a pair of NGK/NTK rear fbody ones, FWIW.
Seems like most recommend the stock AC's, NGK/NTK or Denso. I also read that someone found out at a SEMA show that NGK makes both Denso and AC O2's.....
Here are the O2 part numbers on fbody's and C5's:
NGK/NTK:
- fbody front right: 21528
- fbody rear and front left: 21544
- C5 front: 21006
- C5 rear: 21537
Denso:
- fbody front right: 234-4087
- fbody rear and front left: 234-4025
- C5 front: 234-4012
- C5 rear: 234-4617
AC:
- fbody front right: 25312196
- fbody rear and front left: 25312197
- C5 front: 25312184
- C5 rear: 25317697

Walker Products is the GM supplier for the GM part numbers listed in post #23. Remember, just because it says AC Delco on the box does not mean anything, is could be from Bosch, Denso or whomever was the low bidder for the contract. They change a lot. The numbers list in the post originally were from Delphi and the numbers changed when the supplier changed. The dealer will have all of the supersession part numbers.

i am on my 3rd o2 sensor and still having code p1153, the c5 sensor 13111 has made no difference, im going to get a tune, if you do a search on the code p1153, you will see that the c5 sensor has not solved the problem for most people, and the main reason for this happening is the sensors location is being moved further downstream
