The hotter the air, the more water vapor it can contain. Depending on the circumstances, when the temperature is lowered, that water vapor will condense to the cooler surface. Put a cold glass of beer outside in summer in humid Florida and watch the glass get wet and start forming a ring. Do the same thing in arid Arizona and you don't see any condensation at all.
So, all intercoolers can end up with some condensation, depending on the amount of humidity in the charge air and the temperature. It usually clears up as the air temps rise, via the intercooler itself getting hotter or the humidity subsides. Ford's biggest failure was that the outlet of the intercooler was low enough such that in those situations some of the condensate would get pushed up into the engine. This caused misfires, etc.
It's also why you normally see intercooler tanks on each side, rather than on top and bottom.
