The Toyota MR2 has proven to be a memorable classic with copious amounts of character, unique rear engine setup, and very capable chassis.Keep your MR2 cool with the Mishimoto racing thermostat.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 (160 F) compared to standard thermostats (180 F).This allows coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures.Whether you take your MR2 to tear up the local rally cross or cruise to a show to display your mint condition SC, the Mishimoto thermostat is an ideal upgrade for improving the cooling efficiency of your engine.As with all our products, this thermostat includes the Mishimoto lifetime warranty.
