The Mishimoto racing thermostat for 2008–2012 Mercedes-Benz C63 AMG is a direct replacement that promotes cooler running in stock or modified M156 engines. It opens at a lower temperature than stock to allow coolant flow sooner, reducing and maintaining lower engine temperatures for street or track use. This thermostat activates at 180°F (vs stock 212°F) and includes Mishimoto’s signature Lifetime Warranty.
