Mishimoto Racing Thermostat 154°F 2002-2014 WRX 2004-2021 STI
Mishimoto Racing Thermostats will promote greater cooling efficiency throughout your engine. The Mishimoto racing thermostat will significantly lower the high engine temperature produced by modified and upgraded turbo applications. Once the engine is fully warmed up the Mishimoto racing thermostat will open up at a lower temperature than standard thermostats, also allowing the coolant to flow through the engine sooner thus reducing and maintaining cooler engine temperatures.
