Nismo Radiator Cap

  • Regular price $59.95

NISMO Racing Radiator Cap maintains a higher internal pressure for the cooling system than the standard cap (Valve opening pressure: 0.9kg/cm2 *1.2kg/cm2 for Z32).

It prevents the coolant from boiling and vaporizing easily (the boiling point is approximatery 6°C higher than the standard cap’s 0.9kg/cm2 threshold) and improves cooling efficiency.
