Then just get a six pack ...

 

If you already have one, like I do, the same O2 sensor socket that works on cars, also works on the HD O2 sensors.

Like someone else already said, it's basically a socket with a slot cut out of it for the wiring to slip through.

 

Many auto parts stores sell the socket for around $10.00.

 

I plugged the O2 sensor locations without taking the headers off, had to use the O2 sensor tool just to get to them, the slot allows the wire connectors to turn with the socket. If you are taking the headers off anyway, you don't need the tool because you won't have a problem getting to them and can use a regular end wrench.

 

Since I had to dis-able my O2 sensors for the PCV, I can just throw some plugs in the sensor bungs huh? I should use some ant-seize on the threads right?

 

Yeah, the red stuff.
