Mishimoto 68°C Racing Thermostat for Subaru WRX & Forester (2014-2015)

Optimize your Subaru WRX or Forester's engine cooling with the Mishimoto 68°C Racing Thermostat. Designed for the 2014-2015 model years, this performance thermostat opens at a lower temperature than the stock unit, facilitating quicker engine warm-up and enhanced cooling efficiency. This is especially beneficial for vehicles subjected to spirited driving or track conditions, helping to maintain stable engine temperatures and prevent overheating.

Key Features and Benefits:

  • Lower Opening Temperature: Opens at 68°C (154°F), allowing coolant to circulate through the radiator sooner for improved heat dissipation.
  • Enhanced Cooling Efficiency: Promotes better thermal management by enabling earlier and more consistent coolant flow, reducing the risk of heat soak.
  • Optimized Warm-up: Contributes to reaching the engine's optimal operating temperature more rapidly.
  • Direct Fit Design: Engineered for a precise fit, ensuring straightforward installation as a replacement for the factory thermostat.
  • Durable Construction: Built with high-quality materials to ensure reliability and performance under demanding driving conditions.

Vehicle Fitment:

This Mishimoto Racing Thermostat is compatible with the following Subaru models:

  • Subaru WRX (2014-2015)
  • Subaru Forester (2014-2015)

It also fits select other Subaru models and years, including the 2013-2016 Scion FR-S and later model year Ascents, Legacys, and Outbacks. Always verify fitment for your specific vehicle. Upgrade your cooling system with this essential performance component from Mishimoto, available at GGCRACING.
