Whether you're stuck in traffic or clipping an apex at an autocross, you need a dependable cooling system.An unreliable and inefficient setup can lead to overheating and potential engine damage.Mishimoto is proud to release an all new racing thermostat specifically engineered for your 2002 - 2011 Nissan Sentra.Mishimoto racing thermostats promote greater cooling efficiency by significantly decreasing high engine temperatures.Once the engine is fully warmed up, the Mishimoto low - temperature racing thermostat will open at a lower temperature (177 F) compared to standard thermostats (205 F).This allows coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures.As with all our products, this thermostat includes the Mishimoto lifetime warranty.
