Mishimoto 1.3 Bar Carbon Fiber High-Pressure Radiator Cap, Small Import Fitment (MMRC-13-SMCF)

Maintain optimal cooling system pressure and enhance engine bay aesthetics with the Mishimoto 1.3 Bar Carbon Fiber Radiator Cap. Designed specifically for small import vehicle fitments, this high-pressure cap is an essential upgrade for vehicles pushed to their limits on the track or during spirited street driving.

Standard OEM radiator caps are often unable to handle the increased pressure generated by high-performance cooling cycles, which can lead to coolant leaking into the overflow reservoir. By increasing the system pressure to 1.3 Bar (19 psi), this cap effectively raises the boiling point of your engine coolant, ensuring the system remains efficient and the fluid stays where it belongs—circulating through the engine and radiator.

This cap features a hand-laid carbon fiber exterior for a premium finish and an ergonomic design to facilitate easy installation and removal, even in tight engine bays.
