Mishimoto engineers know you love your Ford which is why we've developed a line of Powerstroke performance parts. A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your 6.4L cooling system with the Mishimoto Ford 6.4L Powerstroke High-Temperature Thermostats! These thermostats are designed as a direct-fit replacement for your aged factory units. 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 Aluminum Radiator for a complete cooling system overhaul. As with all our Powerstroke performance parts, these thermostats include the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship. Whether your Ford is stock or modified, trust Mishimoto and our line of Powerstroke performance parts to keep your Powerstroke cool.
