However, normally the 'ambient' temperature of the air is
higher than the outside air when it reached your cylinders, due
to the heating of the intake manifold and carburation/etc. air
intake systems...
If you have the ability to insulate portions of the air intake
system (carburator from intake manifold, intake manifold from
head, etc.) you can effectively get cooler air into the cylinder...
rather, air which is heated less on the way in...
