Enhanced Cooling for High-Performance Driving

This upgraded thermostat is a game-changer for performance automotive enthusiasts. It significantly improves engine cooling and ensures optimal temperature regulation during high-speed driving. The easy installation process and high-quality design make it a reliable addition to any car. The only downside is the slightly higher price point compared to standard thermostats, but the improved performance is worth the investment. Overall, a great choice for any passionate automotive enthusiast.

Pros
  • Improves engine performance and efficiency by maintaining lower engine temperatures, which can lead to increased horsepower and torque.
Cons
  • May cause engine damage if installed improperly or if not monitored regularly, potentially leading to costly repairs.

It's parts bullshit

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.

Pros
  • Lower activation temperature allows coolant to flow through the engine sooner
Cons
  • Almost everything is fine

Works really well if you have a big heatsink!

First you should upgrade your stock radiator to a larger aftermarket radiator to make this product really worth the noticeable difference. Simply replacing this Mishimoto thermostat will only increase the maximum temperature range. This thermostat will only make your engine cool down faster, but it will not cool down faster or cool down the engine. You will need to replace the stock heatsink with a much larger one for the cooler to work. Where I live May through October temperatures are around…

Pros
  • Fits WRX 2015+ and Forester XT 2014+ models
Cons
