I have an extra set of O2 sensors, but I can not remember if they were post or pre cat o2 sensors. I was wondering if they are the same part number/sensor?

The fronts should have a square pigtail and the rears should have a wider rectangular pigtail.

You sure? I'd almost swear after I deleted my cats I used a rear to replace a front one that went bad it worked jsut fine...

Kragen is showing the same part numbers for both o2 sensors being the same, so I will assume that they are.

The part #s are different but they are totally the same except the wire length.

Sensors and plugs are IDENTICAL....you can use any sensor in any position.....different wire lengths are why they have different part numbers. So measure and buy whatever sensor or brand you like.

I cut my rear plugs off and spliced them into my front wiring harness because my front plugs cracked. They are identical.

agreed, i reused both rear when fronts went bad. other than the wire length they are the same.
