Mishimoto Racing Thermostat Mercedes Benz C63 AMG W204
 
 The Mishimoto racing thermostat for the Mercedes Benz C63 AMG W204 will promote greater cooling efficiency in your stock or modified M156 engine. Once the engine is fully warmed up, Mishimoto's 63 AMG 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.
