B15 and B16 QR25 Mishimoto Racing Thermostat

Mishimoto Racing Thermostat: Mishimoto Racing Thermostats will promote greater cooling efficiency throughout your engine. The Mishimoto racing thermostat will significantly lower high engine temperature produced by modified and upgraded turbo applications. Once the engine is fully warmed up the Mishimoto racing thermostat will open up at a lower temperature than standard thermostats, also allowing the coolant to flow through the engine sooner thus reducing and maintaining cooler engine temperatures.

177 deg vesus OEM thermostats are 205deg and 180deg
