Why Upgrade to a Racing Low Temp Thermostat?

Stock thermostats are designed for emissions and fuel efficiency, not maximum performance. Under aggressive driving or modified setups, heat buildup can limit engine efficiency. Need to service your VQ35DE thermostat? Check out our guide here.

Benefits of a Low Temp Thermostat:

• Lowers engine operating temperature
• Reduces heat soak during spirited driving
• Improves performance consistency
• Ideal for track use and modified engines
• Helps protect engine components from excessive heat

The Mishimoto Infiniti G35 racing thermostat will promote greater cooling efficiency during your engine. A Mishimoto racing thermostat will significantly lower prime 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 usual thermostats, also allowing the coolant to drift in the course of the engine sooner thus reducing and keeping up cooler engine temperatures.
