The 08-10 Subaru WRX Mishimoto Racing Thermostat will promote greater cooling efficiency throughout your engine. Adding a racing thermostat will significantly decrease high engine temperature resulting from modified and upgraded turbo applications. Once the engine is fully warmed up, the Mishimoto racing thermostat will open up at a lower temperature than OEM thermostats. This allows the coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures.
