What do you call the part where you plug in your o2 sensor? It's about 8"-10" long. I think that's what i need to replace and a new o2 sensor.

A few motnhs ago i tried to force the o2 sensor to that metal part thingy because the thread on that metal pipe thingy was all jacked up. so i forced it in.

So, what do you call that metel pipe?
