Keep your Dodge/Jeep on the road and running cool by upgrading to the Mishimoto racing thermostat specifically engineered for the 3.7L/4.7L engines.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 (180 F) compared to standard thermostats (195 F).This allows coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures.Whether your vehicle takes you to work every day or hauls your boat on the weekend, the Mishimoto racing thermostat will keep your engine running cool.As with all our products, this thermostat includes the Mishimoto lifetime warranty.

MIA's Description

The Mishimoto Racing Thermostat is designed to enhance cooling efficiency for Dodge and Jeep vehicles equipped with 3.7L or 4.7L engines. It promotes lower engine temperatures by opening at 180°F, which is lower than the standard 195°F thermostat. This earlier coolant flow helps to reduce and maintain cooler engine operating temperatures. The thermostat is backed by the Mishimoto lifetime warranty.
