Overview

• The NISMO Radiator Cap maintains higher cooling system pressure than the standard 0.9 kg/cm² cap, raising the coolant boiling point by approximately 6 °C.
• This helps reduce coolant boil-over and evaporation under high temperatures, improving overall cooling performance while retaining an OEM-style fit.
