  • Direct fit for the 2015+ Subaru WRX
  • Lower activation temperature allows coolant to flow through the engine earlier, maintaining lower temperatures (Mishimoto thermostat activates at 165.2°F vs. stock 190.4°F)
  • Mishimoto Lifetime Warranty

The Mishimoto racing thermostat for the 2015+ Subaru WRX will promote greater cooling efficiency in your stock or modified FA20DIT. Once the engine is fully warmed up, Mishimoto's 2015 WRX 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 2015 WRX racing thermostat is the perfect addition to your street or track 2015 WRX and is a direct replacement for the stock thermostat. Whether you are entering your 2015 WRX in the local rallycross, or lapping at your next track day, trust Mishimoto and our line of 2015 WRX parts to keep your WRX cool. This thermostat, like our entire line of 2015 WRX parts, includes the signature Mishimoto Lifetime Warranty.
