Optimize your Mazda's engine cooling with the Mishimoto 68°F (20°C) Racing Thermostat. Designed for performance enthusiasts, this thermostat opens at a lower temperature than the factory unit, allowing coolant to circulate through the engine sooner. This results in a more stable and lower operating temperature, which is crucial for preventing heat-related damage and maintaining peak performance, especially in modified or track-driven vehicles.

  • Enhanced Engine Cooling: Helps maintain optimal operating temperatures, reducing the risk of overheating.
  • Durable Construction: Built with high-quality materials for reliable performance under demanding conditions.
  • Direct Replacement: Engineered for a precise fit, making installation straightforward.
  • Versatile Fitment: While primarily designed for the 1989-1995 Mazda RX-7, it also fits a variety of other vehicles, including select Toyota models and Mazda Tributes.

Vehicle Compatibility:

This Mishimoto racing thermostat is an excellent upgrade for:

  • Mazda RX-7: 1989-1995 (FC and FD chassis)
  • Mazda Tribute: 2001-2003 (2.0L models)
