OEM Thermostat

(190 Degree / 2-Stage)

Reduced engine temperatures add life to your engine in either Racing, Off-road or street applications and provide a denser air/fuel mixture which helps produce more horsepower. Consistent control of engine temperature allows an engine to operate at its peak efficiency, no matter what the driving conditions. The factory 195° thermostat simply cycles open and closed, this reduces cooling efficiency in any engine. With the 190° thermostat you get consistent engine cooling and precise metering of water throughout the engine. This thermostat has two valves in it, one closes at the regular temperature and the smaller closes at a cooler temperature. If the cool water shuts the big one, the smaller one will stay open letting coolant into the cooling system.
