Mishimoto 03-06 Nissan 350Z / 03-07 Infiniti G35 155 Deg F/68 Deg C Racing Thermostat

Mishimoto is known for making well-built cooling components, and this racing thermostat is a solid option for your 2003-2006 Nissan 350Z or 2003-2007 Infiniti G35. It's designed to help manage higher engine temperatures, especially if you've added modifications like a turbo. This thermostat opens at 155 degrees Fahrenheit, which is lower than the stock unit.

By opening sooner, this Mishimoto thermostat allows coolant to circulate through the system earlier. This helps to reduce and maintain cooler engine temperatures, which is crucial for preventing overheating, particularly in modified or hard-driven vehicles. It's a straightforward way to improve your engine's overall cooling efficiency.

This thermostat fits a wide range of vehicles beyond the 350Z and G35, including models like the Infiniti FX35 and Nissan Frontier. It's a direct replacement for your factory thermostat, making installation relatively simple for those comfortable working on their cooling system.
