Help reduce your engines temperature and boost horsepower with the JET Performance Low-Temp Thermostat. It's important to know that reducing engine temperatures with a low-temp thermostat not only adds life to your engine but also provides 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 JET Performance 180°Low Temp Thermostat you get consistent engine cooling and a precise metering of water throughout the engine. The JET Performance Low-Temp Thermostat is constructed of stainless steel.
