Black intercoolers/rads, don't things black absorb heat?!
Sorry to state the obvious but I always thought black things absorbed heat?! Always rem my gramps old Morris Marrina with black velour seats burning my legs in the summer!!!
Just wondered why people did it or brought them like it?
Just a aesthetic reason so you can't seem them behind the bumper?

Haven't you ever noticed that the Arabs wear black?
It deflects heat down to their feeties.
I'd have thought that with an intercooler painted black wouldn't matter anyway with the amount of air been pushed into it?

the reason people wear white in hot climes is it reflects the heat better.
Painting a rad black would help a little in the sense that black paint radiates better than light colours.
I do wonder if having the internal surfaces of a radiator phosphated black would help too? I guess it depends if the additional material provides more of a resistance to heat than the additional benefits of the coating being black in the first place.
i wonder this on radiators too if the difference is measurable.

mat black is the best colour to radiate heat it is to do with Stefan–Boltzmann law! (http://en.wikipedia.org/wiki/Stefan%...3Boltzmann_law). roughly speaking it is radaited or absorbed at the difference in temp to the power 4 times a constant!
shiny silver and white are the wost colours for this!
