      Description

      High-Performance Cooling. The Mishimoto Racing Thermostat; 155-Degree is engineered to improve cooling efficiency by opening at a lower temperature than standard thermostats. This enables coolant to circulate earlier, helping reduce elevated engine temperatures often experienced in modified or turbocharged Subaru WRX and STI engines. Effective temperature regulation supports engine reliability and enhances performance during demanding driving conditions.

      Construction and Appearance. Built from durable materials tailored for racing applications, this thermostat ensures consistent performance and long service life. It meets OEM specifications and features a robust finish designed to endure high-temperature environments.

      Installation. Installation difficulty is moderate and requires no drilling. The thermostat is designed as a direct replacement for the factory thermostat, simplifying the upgrade process.

      Warranty. This thermostat comes with a lifetime limited warranty, providing coverage against manufacturing defects throughout the vehicle's lifespan.

      Application. Specifically designed to fit Subaru Impreza models from 2004 to 2014, it supports both WRX and STI trims within this range, offering optimal compatibility.
