Mr Gasket 160 Degree Thermostatá LS1/LS6/LS2/LS3/LS7 2004-13 Corvette
These high performance thermostats are designed to resist large variations in coolant pressures that occur at high RPM's where coolant temperature and coolant pressure fight for control of the thermostat keeping it from opening at it's designated temperature. The balanced HP Thermostat features all brass and copper construction, and opens at the right temperature regardless of engine RPM.
