The Mishimoto racing thermostat for the Lancer EVO 8 / 9 will promote greater cooling efficiency throughout your engine ! Once the engine is fully warmed up the Mishimoto racing thermostat will open up at a lower temperature than standard thermostats, allowing the coolant to flow through the engine sooner thus reducing and maintaining cooler engine temperatures  !
