Review on Mishimoto MMTS-WRX-01 Racing Thermostat for Subaru Impreza WRX/STI 2001-2017 by Ruben Saunders

Revainrating 3 out of 5

Premium Thermostat

This thermostat works as intended and opens much earlier than the standard or other Tstat to start the cooling process. An important note not included in Tstat and why it is there. The Tstat has a small wobble pin, this little wobble plays an important role in the installation as it allows air to pass through. See installation video: [.]
