The Subaru OEM+ STI Radiator Cap is engineered to raise the boiling point of your coolant by maintaining a higher pressure within the cooling system. By holding 1.3 bar of pressure, this cap helps prevent coolant boil-over in high-temperature situations, such as during spirited driving or on the track.
