The Mishimoto thermostats have a lower activation temperature (187°F/197°F) compared to the factory thermostats (192°F/203°F). The lower activation temperatures allow coolant to flow through the engine earlier, which reduces and maintains lower engine temperatures. These thermostats are ideal for use in warmer climates or under extreme towing/driving conditions. Pair this thermostat set with the Mishimoto 6.4L Powerstroke Performance aluminium Radiator for a complete cooling system overhaul.
As with all our Powerstroke performance parts, these thermostats include the Mishimoto Lifetime Warranty, ensuring superior Products quality and craftsmanship. Whether your Ford is stock or modified, trust Mishimoto and our line of Powerstroke performance parts to keep your Powerstroke cool.
