Description 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. Stock caps are not equipped to handle higher pressure, causing fluid to leak out into the overflow reservoir. The Mishimoto High-Pressure 2.0 Bar Radiator Cap will keep coolant where it needs to be- flowing within the system. This cap fits most import vehicles.
