GReddy Radiator Caps
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. Two types are available to fit most Japanese vehicles.

S Type fits most Nissan, Mazda, Subaru, Mitsubishi and some Toyota models
N Type fits most Honda, Acura, and some Toyota models
