Product Details

Chevy Impala LS 2003, Thermostat by JET®. Temperature: 180 Degrees. Jet Low-Temp Thermostats increase horsepower and control engine temp by consistently metering water flow throughout the engine instead of simply cycling open/close, which in OE units creates temperature spikes.


  • Designed to reduce engine temperature and produce more horsepower
  • Made from stainless steel
  • Allows the engine to operate at its peak efficiency
  • Provides a precise metering of water throughout the engine
  • Easy to use

Reduced engine temperatures add life to your engine 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 JET Performance Low Temp Stat Thermostat 180° thermostat you get consistent engine cooling and a precise metering of water throughout the engine. Constructed of stainless steel.

JET® Performance Products, Inc. was started 45 years ago as an engine building and carburetor store specializing in Drag Racing applications. In 1985 Mike Jones, the company’s founder, sold it to its present owner Bryant Seller. The company, led by Seller, got the name 'JET Performance Products' and launched the first performance chips for General Motors applications. Continuing to be a leader in the tuning industry, JET provides a wide range of performance programmers, modules, chips, throttle bodies, accessories, as well as carburetors.
