Interesting test proves that black intercoolers are better at reducing heat soak while you're not moving. This test was done outside a car and away from other heat sources. They also used a hair dryer as the heat source so the temps were significantly higher than we would see in our car, further reducing the real world results. I think there is still a possibility for some advantage of black intercoolers while we're sitting in the queue at an autocross. Maybe a few degrees, could be useful. At least it proved that black is not worse and I was considering black if I decide to upgrade the FMIC.
