Mishimoto has released a racing thermostat engineered to improve the cooling efficiency of your vehicle. Whether you are cruising to a show in your Monte Carlo or lifting the front tires at the strip in your Mustang, an effective cooling system is critical to the life of your engine. Mishimoto racing thermostats promote greater cooling efficiency by significantly decreasing high engine temperatures. Once the engine is fully warmed up, the Mishimoto low-temperature racing thermostat will open at a lower temperature (180 degree Fahrenheit) compared to standard thermostats (195 degree Fahrenheit). This allows coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures. Decreased temperatures will result in reduced engine wear and improved reliability..
