GReddy S-Type High Pressure Radiator Cap - Most Nissan/Subaru/Mazda

SKU: 13911004


High Pressure S-Type Radiator Cap 1.3kg/cm2

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.

Cap installation may feel tighter than stock on aftermarket aluminum radiators. To ease installation push down on the cap as you turn.
