    Features & Details

    • Improves Cooling Efficiency

    Increased Cooling Efficiency. Increase your Jeep’s cooling efficiency when you upgrade to the Mishimoto Racing Thermostat. After it’s installed, the thermostat works to increase your cooling efficiency, whether your 2003 or 2011 2.4L or 3.8L Jeep Wrangler is cruising down the freeway or climbing over rocky terrain. Once your engine warms up fully as you ride, this low-temperature thermometer opens up and lower temperature compared to factory thermostats. The difference is 180 degrees Fahrenheit to the standard 195 degrees Fahrenheit.

    Optimal Air Flow. The Mishimoto Racing Thermostat’s low-temperature activation allows coolant to flow through the engine much sooner than a factory thermostat allows. The result of the improved air flow is an increase in reliability and a reduction in engine wear. That means better performance for a longer life.

    Lifetime Limited Warranty. Mishimoto Automotive warrants this Racing Thermostat under a lifetime limited warranty policy.

    Application. The Mishimoto Racing Thermostat is designed to fit 2003 to 2011 2.4L or 3.8L Jeep Wrangler TJ and JK models.

            Simply Awesome!!!

            Easy install, about an hour time. Keep your engine cooler. Definitely a must if you are in hotter climates.

            Looks just like the picture!

            Part showed up quickly and was exactly as represented in the description. Replacement gasket doesn’t come with it which is a bummer because I’d like to replace that type of stuff while in there, but I was nice to the original gasket so it wasn’t a big deal. Install was a piece of cake.
