Optimal coolant temperatures are crucial for extending and protecting the life of your high-performance Hemi! Protect your investment with the Mishimoto racing thermostat specifically engineered for the 5.7L/6.1L/6.4L Hemi. Mishimoto racing thermostats promote greater cooling efficiency by significantly decreasing high engine temperatures. Once the engine is fully warmed up, the Mishimoto racing thermostat will open at a lower temperature (180°F) compared to standard thermostats (203°F). This allows coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures. Mishimoto thermostats are digitally calibrated, feature high-quality wax to ensure precise and consistent opening temperatures, and include a gasket for seamless installation. Whether your vehicle is stock or modified, the Mishimoto racing thermostat will provide superior cooling efficiency to keep your vehicle on the road and out of the shop. As with all our products, this thermostat includes the Mishimoto Lifetime Warranty
