GReddy high-pressure radiator caps are OEM style caps that directly replace the factory cap. GReddy Radiator Caps have a main valve pressure rating of 127kpa （1.3kg/cm2）which allows for a higher boiling point. A higher boiling point ensures protection against over heating and also ensures your car maximum coolant flow at higher temperatures.
