Toyota MR2 ZZW30 Mishimoto Racing Thermostat

The Mishimoto racing thermostat for the Toyota MR2 ZZW30 will promote greater cooling efficiency in your stock or modified engine. Once the engine is fully warmed up, Mishimoto's racing thermostat will open at a lower temperature than standard thermostats. This allows coolant to flow through the engine sooner, which reduces and maintains cooler engine temperatures.
