Maybe, but there is a 3mm thick plastic gasket separating upper & lower intakes which may serve as a conduction barrier. I think the underside of the upper intake (next to the engine) recieves much more heat than the upper surface. The air must travel a good distance through those runners and I think is picking up a fair amount of heat. Each 10 degree reduction in air temp is worth 1% or 2 HP. Hard to know if this mod will work until someone does it, then measures manifold temps before & after runs with standardized conditions.
True, the gasket may help. But its low conductivity might do very little to offset its thickness. Doubtful you'd see more than a 15 degree gradient across that interface.
Rather than a coating (which may also inhibit the intake's emissive behavior) you might have more luck with a non-contacting radiant barrier between the bottom of the intake and the hot folks beneath.
