SPE Low Temp, High Flow Thermostat SPE-S100119 | 2017–2019 Powerstroke 6.7L

High fluid temperatures are a common issue on 6.7L Powerstroke trucks, especially under load or during towing. The SPE low temp, high flow thermostat provides a simple, engineered solution that effectively reduces coolant, oil, and transmission temperatures (on 2017–2019 models).

The factory thermostat opens at 194/201°F, while the SPE thermostat opens earlier at 175/180°F. This 19–21 degree difference delivers noticeable improvements, with temperature drops of up to 30°F observed during operation. Extensive testing and development have resulted in a cost-effective and reliable upgrade for Powerstroke owners seeking better thermal management.

Benefits: Quick 15-minute installation, thermostat opens at 175/180°F, reduces fluid temperatures by up to 30°F, lowers coolant temperatures, lowers oil temperatures, and lowers transmission temperatures on 2017–2019 models.
