Mishimoto 1.3Bar Radiator Cap Carbon Fibre

By increasing the effective bypass pressure of your radiator cap you can increase the effective boiling point of your engine cooling system.
This means your coolant needs to become hotter before it will start to boil.

Mishimoto has developed a carbon fibre radiator cap to enhance the style of your engine bay while maintaining the pressure in your cooling system. Getting the most out of your performance parts comes down to the details. When faced with hard driving conditions, a vehicle’s cooling system becomes highly pressurized. OEM caps are not equipped to handle higher pressure, causing fluid to leak out into the overflow reservoir.

The Mishimoto radiator cap is rated at a higher pressure and will keep coolant where it needs to be-flowing within the system. The sleek carbon fibre exterior will add an unexpected touch of style. Constructed from hand laid carbon fibre. Rated at 1.3 Bar (19 lbs pressure). Fits most import vehicles.
