2001-2005 Lexus IS300 Racing Thermostat
The Mishimoto Lexus IS300 Racing thermostat will promote greater cooling efficiency throughout your engine. Mishimoto racing thermostats will significantly lower high engine temperature produced by modified and upgraded turbo applications. Once the engine is fully warmed up the Mishimoto 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.
