Lower Coolant Temps for the Supercharged 5.2 - Raptor R High Flow Thermostat

The factory thermostat keeps the Raptor R running hotter than we would like for a performance application. The SPE fix is designed around a 175–185°F operating range withmore flow than the OEM unit, helping the primary cooling system shed heat faster once the thermostat opens. Especially helpful on trucks that spend time under boost, especially pulley, Whipple, or other modified combinations where heat builds quickly.It's a simple way to add more margin to the primary cooling system.
