Fitment Information: This thermostat is a perfect fit for 2015 - 2024 Subaru WRX and 2014 - 2018 Subaru Forester XT. Features: The Mishimoto racing thermostat for 15 - 21 Subaru WRX boosts cooling efficiency in both stock and modified FA20DIT engines. Once the engine is fully warmed up, it opens at a lower temperature (165.2°F or 74°C) compared to standard thermostats (190.4°F or 88°C). This allows coolant to flow through the engine earlier, reducing and maintaining cooler engine temperatures. It's a direct replacement for the stock thermostat, ideal for both street and track WRX. And it comes with the signature Mishimoto Lifetime Warranty.
Using this Mishimoto racing thermostat is easy. First, make sure your engine is completely cooled down. Then, remove the stock thermostat and install the Mishimoto one in its place. It's a direct replacement, so it should fit right in. As for maintenance, keep an eye on your engine temperature regularly. If you notice any unusual changes, check the thermostat. There's no need for special cleaning or treatment. Just make sure it's working properly. And remember, this product comes with a lifetime warranty, so if you have any problems, you're covered. Always follow the standard safety procedures when working on your engine to avoid any accidents.
