Is it necessary to install sound insulation cotton on the engine hood?

[McEmmanuel]

The sound insulation cotton for the engine hood is necessary to install. The primary function of the sound insulation cotton is, of course, sound insulation, followed by heat insulation. It can reduce the heat transferred from the engine operation to the surface of the engine hood. Vehicles equipped with engine hood sound insulation cotton will not produce white mist on rainy days. Excellent heat insulation effect: The sound insulation cotton has excellent heat insulation properties. After being attached inside the car's engine hood, it effectively prevents the high temperature from the engine from directly transferring to the hood, thereby protecting the paint on the hood's surface and avoiding the obstruction of vision caused by mist on the hood during rainy days. Extends the vehicle's lifespan: If chassis sound insulation treatment is performed, the sound insulation cotton's excellent sound absorption and vibration reduction effects will adhere to the chassis, effectively reducing chassis vibrations and eliminating metal fatigue in the chassis.
