The Mishimoto low-temperature racing thermostat for Jeep Wrangler 2.5L, 4.0L and 4.2L applications opens at 180°F—lower than a typical 195°F thermostat—so coolant flows through the system earlier to reduce peak engine temperatures and improve cooling efficiency. Intended to help reduce engine wear, this thermostat is backed by Mishimoto's lifetime warranty.
