1.3bar Radiator Cap

The Mugen High-Pressure Radiator Cap is engineered to enhance your vehicle’s cooling system by increasing the internal pressure of the radiator. This elevation in pressure raises the coolant’s boiling point, thereby improving cooling efficiency—a crucial advantage during high-load conditions such as sports driving.

Key Benefits:

• Increased Boiling Point: By elevating the radiator pressure from the standard 1.1 kgf/cm² to 1.3 kgf/cm², the coolant’s boiling point is raised. This enhancement allows the cooling system to operate more effectively under higher temperatures without the risk of coolant boiling, ensuring consistent engine performance.
• Enhanced Cooling Efficiency: The higher pressure minimizes the formation of vapor pockets within the cooling system, promoting better heat transfer and maintaining optimal engine temperatures, especially during demanding driving scenarios.
• Direct OEM Fitment: Designed to fit stock OEM radiators, the Mugen radiator cap offers a straightforward installation process without the need for modifications, making it a convenient upgrade for enhancing your vehicle’s cooling performance.
