Coolant lines under Intake Manifold?

...that's sweet...

Oui monsieur. Perhaps you're familiar with the exhaust stove, plumbing, and thermostatically controlled damper and/or heat riser valve found on older engines. Same deal. Also, air exiting the TB expands (and thus cools) as it enters the larger plenum. Think expansion valve in an AC system.

Thank you sir.

To answer.

TB is heated to aid in vaporization

Sort of like having a heater grid inside an intake after the intercooler. Constant is the desire.
