The NISMO Racing Radiator Cap enhances cooing capacity by keeping the pressure within the cooling system higher than that of a standard cap, which makes the coolant less likely to boil and evaporate.
The boiling point becomes higher, approximately 6°C, compared to the standard cap's 0.9kg/cm2 threshold.
Fits all Nissan radiators, and most Koyo aluminum radiators.
