Mishimoto MMTS-WRX-01 Racing Thermostat Compatible With Subaru Impreza WRX/STI 2001-2017

Mishimoto 68 Degree Racing Thermostat will promote greater cooling efficiency throughout the engine. The mishimoto racing thermostat will significantly lower high engine temperature produced by modified and upgraded turbo applications. Once the engine is fully warmed up the racing thermostat will open up at a lower temperature than standard thermostats, also allowing the coolant to flow through the engine sooner thus reducing and maintaining cooler engine temperatures.
