Cusco High Pressure Radiator Cap

HIGH PRESSURE TYPE RADIATOR CAP

FEATURE
Raises the boiling point for better cooling efficiency, prevents over heating.

Fortified main pressure valve spring and silicon packing are used to raise the pressure inside the radiator for a higher boiling point. The coolant will not boil easily, prevents air bubbles in the block and radiator core with improved heat transfer.

CUSCO's high pressure radiator caps works at 1.3kg/cm2 at zero atmospheric pressure. In practice though, the atmospheric pressure of the road surface (approximately 1.0kg/cm2) is added and the pressure is 2.3kg/cm2.

There is a chance A or B Type Caps will not suit Mitsubishi  EVO`s. Before purchase, please speak to a licensed tuner to determine the correct cap for your vehicle type.
