  • Activates at lower temperature so coolant flows through system earlier
  • Allows for cooler engine temperatures
  • Mishimoto Lifetime Warranty

The Mishimoto racing thermostat for the 2002-2006 Acura RSX will promote greater cooling efficiency throughout your engine. The Mishimoto racing thermostat will significantly decrease high engine temperature resulting from modified and upgraded turbo applications. Once the engine is fully warmed up, the Mishimoto racing thermostat will open up at a lower temperature (60° C) than standard RSX thermostats (78° C). This allows the coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures.
