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.
