Mishimoto Racing Thermostat for Mitsubishi Evo 7/8/9 — Part #MMTS-EVO-01

The Mishimoto MMTS-EVO-01 Racing Thermostat is a high-performance, lower-temperature thermostat designed specifically for the 2001–2007 Mitsubishi Lancer Evolution VII, VIII, and IX. It is designed to open earlier than the factory thermostat, allowing coolant to begin circulating through the engine sooner and helping maintain lower engine temperatures during demanding driving conditions.

Performance Benefits

The Mishimoto racing thermostat is designed to improve cooling efficiency by opening at a lower temperature than the factory thermostat. Once the engine reaches operating temperature, the thermostat opens earlier, allowing coolant to flow through the cooling system sooner. This can help reduce and maintain lower coolant temperatures, particularly in modified or upgraded turbocharged applications.

The lower activation temperature makes this thermostat particularly suitable for high-performance street cars, modified 4G63 engines, upgraded turbo applications, spirited driving, and track use where additional control of engine temperatures can be beneficial.
