1.3 Bar Radiator Cap

The Koyo Hyper SKC-13 is a high-performance 1.3 Bar radiator cap engineered to complement Koyo aluminum radiators. With an increased valve pressure rating of 1.3kgf/cm2 (18.9 psi), this cap effectively raises the boiling point of your coolant, enhancing the heat capacity of your engine's cooling system and helping to manage excess heat, particularly in high-performance applications. It features a deep plunger type design and is intended for use with Koyorad aluminum performance radiators that have a CNC-machined filler neck. This ensures excellent sealing qualities and leak-free operation. It is crucial to note that this Koyo Hyper Radiator Cap is not intended for use with OEM type radiators that have plastic tanks. Ensure your radiator is compatible before installation to guarantee optimal performance and prevent potential issues.
