The Mishimoto racing thermostat for 2003–2011 Jeep Wrangler TJ/JK (2.4L and 3.8L) lowers the opening temperature to 180°F, allowing coolant to flow sooner than a standard 195°F thermostat. That reduced operating temperature helps control high engine heat and supports improved reliability in street or off-road use. The thermostat is offered with Mishimoto's lifetime warranty.
