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 203 degree thermostat simply cycles open and closed, this reduces cooling efficiency in any engine. With the 180° thermostat you get consistent engine cooling and a precise metering of water throughout the engine. Specifically Designed for the Mopar application.

Opening Temperature Rating: 180 degrees

Upgrade your HEMI’s cooling system with the Speedlogix 180° Thermostat, designed specifically for 2005–2023 Dodge Challenger and Charger V8 engines. By opening at a cooler 180°F, this high-flow, stainless-steel thermostat offers more consistent engine cooling, helping prevent overheating, reducing stress on internal components, and promoting a denser air/fuel mixture — which can support higher horsepower output. Unlike the factory 203°F thermostat that tends to cycle open and closed, this performance thermostat maintains stable operating temperature, improving efficiency and longevity under spirited driving conditions. Engineered for high-performance use and precision metering of coolant flow, it’s a smart upgrade for tuners, track enthusiasts, or any HEMI owner seeking better thermal control, improved reliability, and optimized engine performance.
