Video description

Improve cooling performance and help keep engine temperatures under control with the Mishimoto Racing Thermostat for the 2015-2026 Subaru WRX and 2014-2018 Subaru Forester XT.

Whether your WRX is a daily driver, autocross car, or dedicated track build, the Mishimoto Racing Thermostat is an excellent upgrade to support cooling system performance.

Subaru WRX (2015-2026)
Subaru Forester XT (2014-2018)

Features

Overview  

Fitment Information:

2015 -2024 Subaru WRX

2014-2018 Subaru Forester XT

Features:

The Mishimoto racing thermostat for the 15-21 Subaru WRX will promote greater cooling efficiency in your stock or modified FA20DIT. 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 WRX racing thermostat is the perfect addition to your street or track WRX and is a direct replacement for the stock thermostat. This thermostat includes the signature Mishimoto Lifetime Warranty.

Effective.

Install was not hard at all. Put this on with CSF radiator and Mishimoto cooling fans. Coolant temps in 97 degree weather are 180 and oil temps are 188. Highly recommend this if trying to increase efficiency of your cooling system
