Mishimoto Racing Thermostat WRX (2015-2018) Ford then it is the stockThis Mishimoto racing thermostat will promote greater cooling efficiency in your stock or modified FA20DIT. Once the engine is fully warmed up, the thermostat will open at a lower temperature than standard thermostats. This allows coolant to flow through the engine sooner, which reduces and maintains cooler engine temperatures.
