Review on 🏎️ Mishimoto MMTS-WRX-15 Racing Thermostat: Enhance Performance for Subaru WRX 2015+ (Silver) by Carson Zoberman

This thermostat is bullshit. I installed it on my 2016 wrx and in less than 30 days of careful driving the internal brass assembly cracked in half. The thermostat has NEVER worked as advertised. The temperature was either too high or too low. To top it off, Mishimoto's customer service is the worst. If you want to risk the engine, then do it. Otherwise go to the OEM.
