Hot days at the drag strip or road course will wreak havoc on the cooling system of your Mustang. 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 2011 Ford Mustang V6V8. 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 (160 F) compared to standard thermostats (180188 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.
