    Cooler Runnings. Whether you live in a hot zone or travel through one – or just know you put your Jeep through it’s paces on the trails – it’s important to know you are giving the motor the care and attention it deserves. One of the easiest upgrades you can make to improve reliability in the field is swapping the OEM thermostat for one that opens at a lower temperature. This Mishimoto Racing Thermostat answers the call, opening at 180ºF versus the stock 203º.

    Power and Protection. The Mishimoto Racing Thermostat provides more power for your Jeep on the road or trail by getting coolant circulating sooner when your Wrangler’s engine is under load. This means you can enjoy your drive for longer, finish that job strong, and do it all with the peace of mind that your engine isn’t at risk from the heat.

    Easy Upgrade. This Mishimoto Racing Thermostat is a direct replacement for your Jeep Wrangler JK’s factory thermostat. No special tools or skills are required, and for your convenience a fresh gasket is included in the package.

    Lifetime Warranty. Mishimoto provides a limited lifetime warranty for the 180º Racing Thermostat.

    Application. The Mishimoto Racing Thermostat is intended for use on Jeep Wrangler JK models with a 3.6L engine manufactured from 2012 to 2018.
