Product Description




HKS D1 Limited Edition Radiator Cap




These radiator caps are suitable for many different applications and look great under the hood!

These caps have a higher than standard opening pressure of 1.1 bar to enable the water boiling temperature of the cooling system to be much higher than standard.
