Consistent control of your engine's temperature allows the engine to operate at peak efficiency no matter the conditions. Reducing energy temperatures also adds life to your engine and provides a denser air/fuel mixture which increases horsepower. The factory 195 degree thermostat simply cycles open and closed which reduces cooling efficiency but with the JET 180 degree thermostat you get consistent engine cooling and a precise metering of water throughout the engine. Constructed of stainless steel, the JET Stat Thermostat offers a lifetime warranty.
