The Buddy Club Racing Spec Radiator Caps have pressure capacities of 1.3 x 100kpa (1.3kg/cm2), in comparison to a factory cap that has a pressure rating of only 0.9kg/cm2. This means that the coolants boiling point can be raised by using the Buddy Club Racing Spec Radiator cap. Advantages are of course found on demanding conditions such as circuit racing.
