Raise the boiling point of your coolant for increased cooling efficiency and prevention of overheating with the Cusco High Pressure Radiator Cap. Utilizing a reinforced main pressure valve spring and silicon seals, the internal pressure of the radiator is increased, resulting in a higher boiling point. 

This cap will not fit the BRZ/FR-S twins.

Vehicles listed in the application tab still may not fit this product. Please do your own research.

Skunk2’s Fine Tuning products and accessories, like its high-pressure Radiator Caps, help put the finishing touches onto your vehicle you work so hard to make perform well. Skunk2 Radiator Caps increase internal radiator pressure, which results in a higher coolant boiling point and a more efficient cooling system. Skunk2 Radiator Caps feature an open valve pressure of 1.3 kg/cm—that's .2kg/cm higher than most OEM radiator caps. High-pressure radiator caps like Skunk2’s demonstrate their effectiveness under high-load conditions on both race cars and street cars alike.
