The Mishimoto high-temperature primary thermostat for 2011+ Ford 6.7L Powerstroke raises activation to 199°F/206°F versus stock 194°F/201°F, restricting coolant longer to speed engine warm-up in cold conditions. It is a direct-fit replacement for the primary cooling thermostat and is intended to pair with Mishimoto radiators for improved warm-up behavior and system reliability under demanding use.
