Ok, science is science, but if people are painting their intercoolers and that is it and they are looking at SOLID FACTUAL NUMBERS and they are 20* cooler it must be doing something.
As for the rest of you I thought I was a ricer.....geeez. Why advertise? I suppose if it is a car normally associated with a forced induction sure, don't paint it. But if you have a Supra, or MR2 where most are NOT turbo, or half are not turbo and people ask you if it is a turbo why not paint it?
