High-flow temperature control.
Mr. Gasket high-performance thermostats are designed to resist large variations in coolant pressures that can occur at high rpms. Under these conditions, coolant temperature and pressure fight for control of the thermostat, keeping it from opening at its designed temperature. These balanced high-performance thermostats feature brass-and-copper construction, and open at the right temperature regardless of engine rpm.
