The Mishimoto racing thermostat works with all Nissans with RB engines. It 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.

Digitally Calibrated
Mishimoto Thermostats are digitally calibrated to open at a performance-specified temperature. Precise digital calibration is just one of the steps taken to guarantee that your thermostat will preform time after time, keeping your engine cool.

Japanese Wax
Mishimoto Thermostats are manufactured with a high-quality Japanese wax to ensure that they open precisely and reliably every time. This means you can depend on your thermostat doing its job and keeping your engine cool time after time.

Lifetime Warranty
All Mishimoto products carry a lifetime warranty, including accident prevention. Mishimoto is a name customers can trust to provide a lifetime of performance satisfaction, and with our lifetime warranty customers know we'll always be there to support our products in every way, even if our product is damaged in an accident.
