The Mishimoto racing thermostat for the Scion FR-S and Subaru BRZ will promote greater cooling efficiency in your stock or modified FA20. Once the engine is fully warmed up, the Mishimoto racing thermostat will open at a lower temperature than standard thermostats. This allows coolant to flow through the engine sooner, which reduces and maintains cooler engine temperatures. The Mishimoto FR-S / BRZ racing thermostat is the perfect addition to your street or track FR-S / BRZ and is a direct replacement for the factory thermostat. As with all our products, this thermostat includes the Mishimoto lifetime warranty.

I had never removed a thermostat and it opened the flood gates of coolant. After cleaning up however my 2015 wrx now runs between 190 and 205. Stock I was between 207 and 215 so much cooler operating temperature.
For my EU Spec 2018 STI works great (no check engine light)! I live where temperatures are all year long 24ºC (75ºF) lowest to 38ºC (100ºF) heights and moreover since I drive on heavy traffic most of the time.I recommend it for hot weather temperature
Definitely does the job, engine runs much cooler. You might get a check engine light though, P0128, so you will have to adjust the ECU to account for the cooler temps.
Only reason I gave 3 of 5 for ease, it can be a bit messy.
