Warm Air Intake - Intercooler as an intake heater

[Daox]

So, would using the throttle body heating circuit be a good choice for this intake heater idea?

I don't see why not.

Not trying to pick a fight but not all vehicles run coolant through the throttle body.

I'm curious which cars you've seen without warmed throttle bodies? I can't recall ever seeing a fuel injected engine without.
