O2 Sensor Extender for Passenger Cat
 

My 05’s passenger side O2 Sensor wouldn’t reach where it previous went after my clutch install, so I decided to buy O2 Sensor Extenders for the wiring.

It looks like a simple plug and play kit with no actually wiring involved, I just don’t know how I would go about doing this “install,” or how to actually get to it with my bell housing on if I had to go under the car.

Bump

A little more info would be helpful. Did you also install long tube headers, with or without high flow cats? Which O2 sensor, the front or the rear? What has caused the original wire to not reach, is it misrouted?

nothing aftermarket, just when I went to re-install the cats after my clutch job, cord didn’t reach to its port.

it’s the front passenger.

when I was down there I couldn’t figure out why it wouldn’t reach.

Although the extensions are plug and play, you should not need one. The front O2 sensor is visible from the engine compartment in between the middle cylinders on the exhaust manifold, its cable comes from under the plastic fuel rail covers. Are you referring to the O2 sensor that is behind the cats, if so its wire is located underneath the car.

I mean the O2 Sensors that literally plug into the cats

Your configuration must be different than my 2006. My upstream O2 sensor goes in the exhaust manifold on top in between the center cylinders, my cats bolt directly to the bottom of the exhaust manifold and the cats have a length of pipe coming down where the downstream O2 sensor is, right before where it bolts to the H-Pipe.
