JURAN Racing Carbon Insulator

Carbon felt prevents heat from entering the car.

High insulation performance is achieved by layering aluminum foil on carbon felt. It blocks the heat from the engine and transmission that is transmitted to the inside of the car through the floor.
Attaching it to the battery prevents it from overheating in the summer and getting too cold in the winter.
If installed in the intake system, the intake air will be less likely to get overheated, preventing deterioration in engine performance.

Performance of each material (heat resistance temperature)
Carbon felt: No melting point
Aluminum foil: Melting point 660℃
Adhesive: Boiling point approximately 100℃ (Be careful of the heat on the mounting surface)
