Default yes and no

yes you can run 4 rear o2 sensors for the length of the wiring, but to run them in the front positions you need adapters. Most people however just have the rears tuned out and just run the rear 02 sensors adapted to go in the front positions. This is of course if you are talking that you now have headers.....which I assume you do.

Don't know the answer to your question, but have a couple suggestions:

American Racing headers use extensions, not adapters... Can't get some from them?

Or RockAuto carries both electrical connectors. You could just make your own...

Good luck,
Vaughn

You realize the LG headers are not legal in Cali ??? If the tech doing your smog check spots the headers during the visual part of the inspection, you could have a problem on your hands .... some catch it, some don't .... it's a crap shoot ....

Good luck,

Contact Anthony at LG motor sports He can hook you up with the right
extensions. They should have the extensions you need. I have an 04 Z
and run all 4 O2's in there original position.

The AR header system for the C5 doesn't include extensions, nor are they required. The stock lengths fit fine.
