NOTE: Check year of vehicle and application notes.


The Mishimoto Nissan racing thermostat will promote greater cooling efficiency throughout your engine. A Mishimoto racing thermostat will significantly lower high engine temperature produced by modified and upgraded turbo/super-charger 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.
