Cusco 1.3 Bar A-Type High Pressure Radiator Cap | 00B 050 A13

Raise the boiling point of your coolant for increased cooling efficiency and prevention of overheating with the Cusco High Pressure Radiator Cap. Utilizing a reinforced main pressure valve spring and silicon seals, the internal pressure of the radiator is increased, resulting in a higher boiling point. 

When coolant boils, small air pockets are created. As the coolant passes through the block and radiator core, the air pockets reduce the cooling efficiency and will eventually cause the engine to overheat. 

Note: Operates from 2.3kg/cm2 Boiling point approximately 126.5 Degrees Celsius

Does NOT Fit BRZ or FRS
