Ceramic coating, intake manifolds

[Richard Hoffman]

Hello All!
I don't have a terribly important question...but I was always under the
impression that ceramic coating an intake manifold helped lower intake air
temperatures by reflecting radiant heat in the engine bay.

Just recently (on an internet chat board, told you it wasn't that important)
I was told that the intake manifold is supposed to act as a heat sink and
absorb heat from the intake air.  This sounds totally backwards from
everything I've ever heard.  We're not talking some crazy intercooler/intake
manifold combo, or even a forced induction application.  Just a regular old
cross-flow 4v motor (use a 7A as an example).

Just looking for confirmation that the person who told me that is a dolt.
Feel free to doltify me, if appropriate!
