Also, for intercoolers, the touch test may not actually show anything.

A hot to the touch intercooler is an intercooler that exchanges a lot of the heat with the air. It gets hot and cools down the air passing through.

A cold to the touch intercooler is more "insulated" to the air passing through, exchanges less heat, remains cooler and leaves the air passing through hotter.
