STI High Pressure Radiator Cap 11815AB213 and oil consumption yet strengthCOOL UNDER PRESSURE The STI high pressure radiator cap helps keep the coolant within the engine under extreme driving conditions. This cap increases maximum system pressure from 108kPa (15. 7psi) to 130kPa (18. 9psi) to ensure that the system will not overflow under conditions of increased coolant thermal expansion. Higher system pressure also increases the coolant boiling point. Please ensure all hoses and clamps are in excellent condition before
