I have a 1997 honda civic hatch dx with a d16y7 and i got new headers for it. And the hole for the 2nd o2 sensor is back farther then the sensor will reach, so i was wondering what gauge these wires are?
If anyone knows it would help alot, thanks

 

DC headers come with 02 extensions if I was you I would give them a call or anybody that carries this brand and see if they can sell you one.
