The Mishimoto thermostats have a higher activation temperature (198°F/208°F) compared to the factory thermostats (192°F/203°F). The higher activation temperatures restrict coolant flow longer to allow a quicker engine warm-up, making these thermostats ideal for use in cold climates. 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.
