Z1 Motorsports High Pressure Radiator Cap for all Nissan and Infiniti models including the 300zx, 350z, G35 and 240sx.
By increasing the pressure within the coolant system, you can thereby lower the boiling of coolant itself. In other words...Your car will run cooler! Located on the radiator, the Z1 Motorsports High Pressure Radiator Cap replaces the stock cap which has a factory relief pressure of 1.2 Bar (17.4 PSI) with a unit with a relief pressure of 1.37 Bar (19.9 PSI).
Produced with OEM quality, but with the performance advantages of an aftermarket radiator cap.
