Koyo Radiator Cap - Type A (Red / 1.3 Bar)

Universal SK-C13 Radiator Cap by Koyo

If you just purchased the Koyo Radiator, you can maximize the performance with the Koyo 1.3 Bar High Pressure Radiator Cap! These are finished in Hyper Red, and reviewers of this radiator cap have been pleased with the looks, and performance of this radiator cap.

This Koyorad Hyper Cap withstands an increased valve pressure rating of 1.3kgf/cm2 (1.3 bar) (18.9 psi) (130 kPa) which increases the boiling point of water and relieves high performance engines of excessive heat. These are highly recommended for use with every KoyoRad All Aluminum Radiator (when applicable).

Why is increased Pressure Better?
It’s simple. When water is pressurized, its natural boiling point is increased. Most modern vehicles are equipped with a 0.9 Bar pressure cap. Koyorad’s Hyper Cap is rated at 1.3 Bar which increases the boiling temperature of your coolant to 267.80 degrees Fahrenheit. That is nearly a 56 degree increase over water's normal boiling point. By increasing the boiling point of water, an engine's cooling system will have the added heat capacity, maximizing perfromance under ever-changing racing conditions.

The KoyoRad Hyper cap is crafted in Japan from high quality materials to ensure longevity and performace from your KoyoRad Racing Radiator.
