    Description

    Protect that Power. If you're adding some bolt-on performance to your mustang, you're adding more heat and power loads. The Reische Performance Thermostat operates at 170 degrees compared to the 180 to 195 degrees of your OEM unit, which allows your motor to run cooler, longer, under higher output. Installing this thermostat is a simple but critical investment in protecting your engine.

    Tune it? Cool it. If you're advancing timing on your motor or operating a custom tune, a lower temperature thermostat is a critical investment in engine life. Lower temperatures allow for safer timing advancement and tuning without causing engine wear or detonation, which can ruin your motor.

    Made to Fit Mustangs. Unlike cheaper, generic units that are "universal", each Reische Performance Thermostat is made using the same diaphragm and bypass control as OEM thermostats. Each unit is modified by hand with U.S made parts to ensure they run at the right temperature for your Mustang.

    All-Weather Capable. Running a lower temperature thermostat has been said to reduce performance – but with the Reische's consistent operation and 170-degree "sweet spot", no drivers have reported any loss of power or MPGs in colder weather.

    Application. The 170-Degree Reische Performance Thermostat is specifically designed as a direct replacement-upgrade for all 2011-2020 GT, V6, GT350, and 2012-2013 BOSS Mustangs.

    Tuning Note. While no tuning is required for installation, we do highly recommend lowering your fan settings for more consistent coolant temperatures.
