Subaru OEM STI 1.3 Bar High Pressure Radiator Cap Pink

Improve your cooling system while spicing up your engine bay with a Subaru Genuine Cherry Blossom Rose radiator cap. This cap is a higher pressure then the cap that came stock on your vehicle. By raising the pressure in the cooling system you raise the temperature at which it boils allowing it to hold in more heat. Some Subaru models have 2 caps, if you are trying to improve your cooling system you will need to replace both caps.

This cap will not fit the BRZ/FR-S twins.
