Maximize your Subaru's performance with the Mishimoto High-Pressure 1.3 Bar Radiator Cap. When pushing your vehicle under demanding driving conditions, the cooling system becomes highly pressurized, often exceeding the limits of stock caps. This leads to coolant loss into the overflow reservoir, compromising performance. Engineered specifically for Subaru vehicles, with one-way functionality matching the OEM radiator cap design, guaranteeing appropriate operation of your Subaru's cooling system. The Mishimoto cap maintains optimal coolant flow by withstanding higher pressures. Its direct-fit design ensures easy installation, and the unique, non-directional sticker means it's always facing the right way.
