  • NOTES
  • NOTE1: These high-performance items are not eligible for any further discounts or promotional pricing.

These high-performance thermostats are designed to resist large variations in coolant pressures that occur at high-rpm's where coolant temperature and pressure fight for control of the thermostat keeping it from opening at its designated temperature. The balanced HP thermostat features all brass and copper construction and opens at the right temperature regardless of engine rpm.
