FORD-50 GEN-2 170°F Thermostat
SKU: RP-FORD-50
Easy — 1–2 hours
Overview
This thermostat provides better performance than many competitor 160° thermostats. Reische recommends a 170° opening temperature as the ideal balance for high-performance engines, allowing for high radiator flow by mid-180°F temperatures. This offers added protection against detonation and maximizes horsepower, especially for engines running high timing or boost. It comes with a 5-year warranty.
