Koyorad Hyper High Pressure Performance Radiator Caps increase the coolant pressure allowing greater efficiency of the cooling system.
Why is increased Pressure Better? - When water is pressurised, its natural boiling point is increased. Most modern applications are equipped with a 0.9-1.1BAR pressure radiator caps. Koyorad Hyper High Pressure Radiator Caps are rated at 1.3BAR which increases the boiling temperature of the coolant to 131ºC and that is a 31ºC increase over waters natural boiling point. By increasing the boiling point of water, the engine’s cooling system will have the added heat capacity, maximising performance under racing conditions.
Made in Japan using the highest quality components ensuring the best performance possible.
A much needed upgraded for those who plan to do track days or circuit racing.
For use with Koyorad Racing radiators.
Pressure increased to 1.3kgf/cm2.
