I think those inner fenders from Metal Cloak would be good for heat reduction, but im not sure about how much heat is going out of the channels of the RKsport hood.

The hood takes the air and forces it down to the intake, which is fantastic for cold air, but for helping hot air escape im not so sure. The perhaps at high speeds, the hood would force the hot air of the engine bay out thru the inner fenders, and at low speeds, the hot air may escape through the intake to the rear vents.

My meaning is, you can see the large vents in the rear of the hood. You'd think they were great for heat reduction, but they are not directly open to the engine bay. They are connected to channels that lead to the nose, and to the intake.
