Mishimoto Thermostat | 2001-2014 Subaru WRX & 2004+ Subaru STI

Thermostat by Mishimoto

The Mishimoto racing thermostat for the Subaru WRX 2001–2014 / STI 2001–2016 will promote greater cooling efficiency throughout your engine. The Mishimoto racing thermostat will significantly lower 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.

  • Activates at lower temperature so coolant flows through system earlier
  • Allows for cooler engine temperatures (68 Degree Celcius)
  • Mishimoto Lifetime Warranty
