TPI Intake Manifold Bolt identification
I broke off a bolt/plug on the TPI intake manifold that has a built-in electrical connection in it. I need to ID it so I can replace it.
It is at the very front of the manifold, way under the throttle body. There is a two pronged connection that plugs into the center of the bolt. If you unscrew it, all the coolant will come out of the manifold. Anyone know what this thing is called/where I can get one? Its the thing circled in RED on the picture.
Thanks!

That's not a bolt, that's a coolant temp sensor (CTS). It's for the ECM so it knows how hot the coolant is.
