Description
the 08-10 Subaru STI GrimmSpeed 160 Degree Thermostat will make an immediate and direct impact on your engine running temps. The 160 degree T-Stat will bring your engine coolant temps down 20-30 degrees. In turbo’d applications, the engine coolant must also cool both the turbo and the engine oil. This places a greater strain on your oem thermostat, in which the GrimmSpeed 160 degree T-Stat can handle.
