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 180 Aluminum Radiator, your Fiesta will maximize cooling efficiency. This Fiesta thermostat, like all our Fiesta ST 180 parts, includes the unparalleled Mishimoto Lifetime Warranty.
