Mishimoto Performance Thermostat - 74C/165F Subaru WRX 15+

The Mishimoto racing thermostat for the 2014-2018 Subaru Forester XT will promote greater cooling efficiency in your stock or modified FA20DIT. Once the engine is fully warmed up, the Mishimoto racing 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. The Mishimoto Forester XT racing thermostat is the perfect addition to your street or track Forester XT and is a direct replacement for the stock thermostat. As with all our products, this thermostat includes the Mishimoto Lifetime Warranty.
