Hypertech 160 Degree Thermostat

A cooler running engine improves performance by increasing the mass air flow rate of intake air and by reducing the engine's tendency to detonate. Reduces the temperature of both the incoming air/fuel mixture and the surfaces of the combustion chamber allowing the engine to safely develop more horsepower. Easily installs in 30-45 minutes with normal hand tools. 2-stage design with integral housing, made specifically for the LS1 engine.
