NISMO 40TH Anniversary Radiator Cap Poster Outer diameter φ45This racing radiator cap improves cooling performance by keeping the pressure in the cooling system higher and making it harder for the coolant to boil or evaporate compared to the standard radiator cap. Compared to the standard cap with an opening pressure of 0. 09MPa (0. 9kg cm2), the boiling point is increased by approximately 6 C. The design that was on sale in the 1990s has been reproduced on the top surface of the current racing radiator cap.
