Mishimoto Dodge/Chrysler/Jeep Hemi 5.7L/6.1L/6.4L Racing Thermostat

If you're looking to keep your high-performance Hemi engine running cooler, especially under demanding conditions, a lower-temperature thermostat can make a notable difference. This racing thermostat from Mishimoto is specifically designed for 5.7L, 6.1L, and 6.4L Hemi engines found in a wide range of Dodge, Chrysler, and Jeep vehicles, including models like the Dodge Charger, Chrysler 300, and Jeep Grand Cherokee.

Unlike a stock thermostat that typically opens around 203°F, this Mishimoto unit opens sooner at 180°F. This earlier opening allows coolant to circulate through the system more quickly, which helps to significantly reduce and maintain lower overall engine temperatures. This improved cooling efficiency is beneficial whether your Hemi is stock, modified with a camshaft, or boosted with a supercharger, helping to extend engine life and ensure consistent performance.

This thermostat is a direct replacement for your factory unit, making installation straightforward. It's a well-built component designed to help your Hemi perform at its best by keeping temperatures in check.
