The Mishimoto racing thermostat for the 2009-2011 Nissan GTR will promote greater cooling efficiency for twin turbocharged engines. The Mishimoto street thermostat opens at a lower temperature than OEM thermostats to maintain optimal temperatures, even under extreme driving conditions. Once the engine is fully warmed up the Mishimoto GTR thermostat will open up at 66 C, allowing the coolant to flow through the engine sooner thus reducing and maintaining cooler engine temperatures..
