Thermostat 160 Degrees GM LS1

The MR. GASKET Thermostat 160 Degrees for GM LS1 engines is a precision cooling system component engineered to maintain optimal engine operating temperature in high-performance LS-series applications. This brass and copper construction thermostat opens at 160 degrees Fahrenheit, providing aggressive cooling management for vehicles running modified power levels, track applications, or consistently demanding driving conditions where factory thermal limits prove insufficient.

The 160-degree opening temperature is significantly lower than OEM specifications, allowing coolant circulation to begin earlier in the warm-up cycle and preventing heat buildup during sustained high-RPM operation. Brass and copper materials resist corrosion and offer superior thermal conductivity compared to alternative designs. LS1 engines in performance vehicles—whether naturally aspirated, supercharged, or turbocharged—benefit from this lower-temperature thermostat when cooling system capacity or ambient conditions create risk of overheating. The compact design fits directly into factory LS-series thermostat housings without modification.

MR. GASKET is recognized in the LS-engine performance community for producing OEM-compatible cooling components that bridge the gap between stock cooling adequacy and aftermarket system requirements. This 160-degree thermostat is suitable for track enthusiasts, street racers, engine builders, and LS1 platform owners seeking reliable thermal management without full system replacement. Installation is straightforward, requiring only removal of the factory thermostat housing and substitution of this component.

Part number 6367 carries MR. GASKET's manufacturing specification and is confirmed by UPC 084041017227, ensuring correct fitment for GM LS1-series applications across multiple platform years and configurations.
