This low-temp thermostat dramatically reduces operating temperatures, while increasing thermal efficiency and your engine's performance in the process. Racers know that a cooler running engine is a better performing engine. This new thermostat replaces the factory unit, allowing coolant to circulate at lower engine temperatures, keeping the engine cooler. Fits the following applications:

  • 2004-06 4.8L/5.3L/6.0L Silverado/Sierra/SUV/2007 Classic (GM/GMC Truck/SUV 800 Series)
  • 2004-06 LS1/LS2 Pontiac GTO
  • 2004-08 LS1/LS6/LS2/LS3/LS7 Corvette
