Description
Keep your Fiesta running cool with the Mishimoto low-temperature Fiesta ST thermostat. Optimal engine temperatures are imperative to achieving peak performance. This Fiesta ST thermostat activates at 160°F vs. the stock 207°F, allowing the coolant to flow through the engine earlier. When you’re out hot lapping at the track, a lower temperature thermostat will be beneficial in keeping engine temps down. When paired with the Mishimoto Fiesta ST Aluminum Radiator, your Fiesta will maximize cooling efficiency.
