Mishimoto Nissan RB 155 Deg F/68 Deg C Racing Thermostat

This is the Mishimoto Racing Thermostat for Nissan RB engines. It's designed to open at 155 degrees Fahrenheit (68 degrees Celsius), which is lower than a stock thermostat. This means coolant starts flowing through your engine sooner, helping to keep temperatures down, especially in modified or turbocharged applications where engines can run hotter. You get the thermostat itself, ready to install.

When your engine is fully warmed up, this thermostat will activate earlier. This earlier flow helps manage and maintain cooler engine temperatures, which can be beneficial for overall engine health and performance under load. It's a well-built part from Mishimoto, known for their cooling system components.

This thermostat fits a wide range of Nissan and Infiniti vehicles, including models like the 1984-1996 Nissan 300ZX, 1985-1994 Nissan Maxima, and 1993-1997 Infiniti J30. Always check the full fitment list to confirm it's right for your specific car.
