Mishimoto Racing Thermostat 154 Degree - Most Subaru Models

The Mishimoto racing thermostat for Subaru will promote greater cooling efficiency throughout your engine. Mishimoto racing thermostats will significantly decrease high engine temperatures 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 (68°C) than standard thermostats (82°C). This allows the coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures.
