Lingenfelter Performance 160° thermostat for 2009-2013 Corvette C6 Corvette LS3 6.2L, Z06 LS7 7.0L and ZR1 LS9 6.2L SC. 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.
