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 overheating and also ensures your car maximum coolant flow at higher temperatures. Two types are available to fit most Japanese vehicles.
