Boost Cooling System Pressure for Improved Performance. The Mishimoto High-Pressure Radiator Cap is a valuable upgrade for vehicles operating under higher-than-average engine temperatures or demanding driving environments. By increasing the system pressure to 1.3 bar, this cap raises the coolant's boiling point, effectively enhancing your radiator’s ability to manage heat. This leads to a more stable engine temperature, especially in racing, towing, or off-road scenarios where traditional caps may fall short. It’s a simple enhancement that can contribute to a more resilient cooling system under stress.
Reliable Construction for Long-Term Use. Constructed with a high-grade steel body and a precisely engineered internal pressure valve, this radiator cap ensures consistent sealing and dependable operation over time. The rubber gasket is designed to maintain a tight seal, even under extreme heat and vibration. Its universal design makes it adaptable to many applications that require a large-style cap, although minor adjustments may be needed. Ideal for both modified and stock cooling systems that require an extra level of performance and reliability.
Installation. This product installs by threading onto a compatible radiator filler neck. Always confirm the correct size and pressure rating before installation to ensure proper function.
Application. This Mishimoto High-Pressure 1.3 Bar Radiator Cap; Large fits universal applications. Some adaptation may be required depending on the radiator type.
