09-13 160 Degree Thermostat - LS3 / LS7 / LS9

These low-temp thermostats dramatically reduce 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. Not legal for use on pollution controlled vehicles.
