Bolt-on Protection. Bolt-on mods mean easy power, more fun... and more heat. More heat means more engine wear, and you don't want to kill the fun - or your motor. The Reische Performance Thermostat operates at 170 degrees compared to the 180 to 195 degrees of your OEM unit, reducing engine temps quicker to prevent damage from bolt-on performance gains. This simple safety investment, then, is a must-buy. 

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 1979-1995 5.0L and 1979-2004 V6 Mustangs.

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