Description
For the – Subaru WRX 2001-2014, WRX STI 2004-2017 (60 Degrees), this thermostat is a practical way to adjusts the temperature point at which coolant circulation increases through the radiator.
Why consider this upgrade
Its value is greatest when matched with adequate radiator capacity, healthy fans, proper coolant service, and the way the car is actually driven. On this performance platform that can generate substantial heat under repeated load, that matters most when the vehicle is used for tuned street builds, canyon driving, autocross, roll-on acceleration, and track days.
Because this listing is specific to the – Subaru WRX 2001-2014, WRX STI 2004-2017 (60 Degrees), it should be evaluated alongside the vehicle’s current cooling, airflow, power, tire, and track-use setup as applicable.
Enthusiast profile
Who benefits most: track or high-load drivers using complementary radiator and fan upgrades. This is particularly appropriate when reliability, repeatability, and driver confidence matter more than chasing a single peak number.
