Exactly which O2 sensors do I need?
Getting odd codes from o2 sensors, so I was thinkg about repl seeing I do not know how old they are anyway. Motor is LS2 in '02 Z06 with FLP headers. Currently there are only 2 sensors before the cats. If I understand things correctly, then I would need the rears? Would that be the heated ones $40.50 for Delco, or the other ones $90.50 Delco? TIA.

Car had been running fine. I found some shorted wires in the pigtail that goes to the MAF and fixed them so no codes. I still wouldn't mind changing the O2s just so I could have a back up at the track. I didn't put my headers on, so I am not sure which ones I need - the post catalytic ones or pre-catalytic. From my search, it seems everyone moves the rears to the fronts.
