Description

The Mishimoto Racing Thermostat is a direct-fit replacement designed for the 2014-2019 Ford Fiesta ST. It features a lower activation temperature of 160°F compared to the stock 207°F. This allows coolant to flow through the engine earlier, helping to maintain lower engine temperatures, especially beneficial during track use.

The thermostat includes a spring plate, spring, and two rubber O-rings. Mishimoto offers a lifetime warranty on this product.
