What is under-hood insulation?

Under-hood insulation are panels or pads installed under a car’s hood to protect components from the engine’s heat, says Edmunds. Insulation kits are pre-cut to easily fit the engine’s contours under the hood and may be customized to feature vehicle brand names.

Under-hood insulation lowers the risk of damage to a painted hood by providing a cushion against excessive and corrosive engine fumes. The panels are heat-resistant to regulate temperature under the hood by dispersing heat evenly. QuietRide notes the insulator dampens engine noise for a quieter ride. The kits dress up a car’s under side and make it more appealing while minimizing vibrations.
