Prova Sports 1.3 Bar Radiator Cap
Raise the boiling point of your coolant for increased cooling efficiency and prevention of overheating with the Prova 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.
This cap will not fit the BRZ/FR-S twins.
Vehicles listed in the application tab still may not fit this product. Please do your own research.
