The Mishimoto high-temperature thermostat set for Ford 6.4L Powerstroke is a direct-fit replacement that raises activation to 198°F/208°F versus factory 192°F/203°F, restricting coolant flow longer for a quicker engine warm-up. Supplied as a pair with a replacement gasket, these thermostats are intended to improve warm-up behavior in cold climates and integrate with other Mishimoto cooling upgrades.
