Upgrade your cooling system with the HKS 1.1 Bar Radiator Cap, a simple but effective performance upgrade designed to improve cooling efficiency under demanding driving conditions. Manufactured by HKS Japan, this radiator cap increases the cooling system pressure compared with many OEM caps, helping prevent coolant boiling and maintaining stable engine temperatures.
The cap features a 1.1 bar (108 kPa / 1.1 kgf/cm²) pressure rating, which raises the coolant boiling point and allows the cooling system to operate more efficiently during spirited driving or track use.
Constructed with high-quality seals and durable metal components, the HKS radiator cap also adds a clean motorsport-inspired appearance to the engine bay with the signature red HKS logo.
