Mishimoto racing thermostat for the 2003-2006 Mercedes-Benz AMG M113 5.4L supercharged engine (E55, C55, S55, CLS55, SL55, G55 AMG). It opens at 180°F — lower than the stock 188.6°F — so coolant flows earlier to reduce and maintain cooler engine temperatures on street or track. Direct-fit replacement, backed by the Mishimoto Lifetime Warranty.
