Mishimoto high-temperature thermostat set for the 2008-2010 Ford 6.4L Power Stroke diesel. The higher 198°F / 208°F activation temperatures (vs. factory 192°F / 203°F) restrict coolant flow longer for a quicker engine warm-up — ideal for cold climates. Direct-fit replacement for both factory units; includes both thermostats and a replacement gasket, backed by the Mishimoto Lifetime Warranty.
