Fits Nissan 300ZX 1991-1996 and all other RB Engines

The Mishimoto Nissan 300ZX racing thermostat will promote greater cooling efficiency throughout your engine and 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.
