Product Description

The Mishimoto MMTS-EVO-10L Racing Thermostat is a direct-fit performance cooling upgrade designed specifically for the **2008-2015 Mitsubishi Lancer Evolution X** equipped with the 2.0 L 4B11T turbocharged engine. Unlike the stock thermostat that opens at a higher temperature, this performance unit begins opening at approximately **154.4 °F (68 °C)**, allowing coolant to circulate earlier and helping reduce peak engine operating temperatures under load. This earlier flow helps improve overall heat management, especially in modified or high-performance turbo applications.

Engineered to replace the factory unit without modifications, the MMTS-EVO-10L installs in the original thermostat housing and supports both street and track use with improved cooling efficiency. Its direct-fit design ensures proper sealing and operation with the Evolution X cooling system, and the Mishimoto Lifetime Limited Warranty offers peace of mind. Whether you're driving a stock Evo X or a heavily tuned turbo build, this racing thermostat helps maintain more consistent and controlled engine temperatures.
