Mr. Gasket 1998-02 LS1 160 Degree Thermostat (New Style)

LOWER YOUR ENGINE TEMPS FOR MORE POWER!

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.

**Please note these will only fit the newer style LS1 Waterpumps.
