You will either need extensions for your front O2's or you can buy rear o2's for a c5 (bosch 13111) because they have a better heating element and longer wires. You won't need extensions if you use Bosch 13111's, and you are less likely to get a heater circuit trouble code.

The reason for the above is because your front oxygen sensors will be much further away from the motor than they are on stock manifolds.

As for rear O2's, you either need simulators or a computer tune to delete them if you don't want your check engine light coming on.

You need extensions to connect YOUR existing front O2's, OR buy Bosch 13111 O2 sensors which already have longer wires on them, that'll take care of the front ...

Your tuner will shut off the REAR O2's in the PCM so you dont have to do anything back there, it will set a code until it's tuned though. You don't need O2 simulators if you are going to get a tune.

Couldn't you just lengthen the wires on the original O2 sensors?

Yes you can lengthen the wires (the pacesetters come with wire) it's up to you, you can
1 Get vette o2s (bosch 13111s) and not have to make the extensions
2 Use the premade extensions
3 Lengthen the wires yourself using the wire included with the pacesetters
You only need to use one of the above three choices

Well the boschs can help with the slow switching codes, that can occur with the stock 02s in LT applications, it's your call, I went with the boschs, and haven't had many codes thrown (only when it's cold outside)

You can usually get them at most any chain parts store (autozone, oreillys, pep boys, advanced, napa), they go for about $69/ each
Just ask for the corvette rear o2 sensor, bosch p/n 13111
