Heat is known to be a common enemy of power. Keeping both intake and coolant temps low are a good idea on basically every application. The Ratstat 170-degree thermostat will give you the low coolant temperatures needed to get the most out of your Ford vehicle. Having a lower temp thermostat, means coolant flowing earlier and then when coupled with the correct calibration fans kick on earlier as well. An upgraded thermostat is one of the most commonly recommended products by MPT. Cooler temps allow more consistent power and prevent the power loss associated with hotter temps. The ratstat includes a 2-year manufacturers warranty.
NOTE: This 170-degree thermostat is a different size and designed differently than the OEM thermostat. This is due to a different gasket being used in the construction of the thermostat. Install as is and it will fit correctly.
