Insulation under the hood can prevent engine heat. It doesn't let the heat go through and destroy the color of the car's hood, or some people think it can help reduce engine noise. The hood gets more sunlight than the rest of the car. Especially when the paint is dark, when parking in the sun for a while, the heat from the sun will cause the hood to have more heat than it gets from the engine. Installing insulation under the hood will prevent the heat from the engine from transferring to the hood.
     This insulation will allow more heat to accumulate in the engine than usual. It can also prevent engine noise from entering the cabin because the insulation is soft to help absorb sound waves. However, whether it's the heat from the sun or the heat from the engine, the color of the car's hood must be quality paint to tolerate the heat.
