            Product Description

            The Mishimoto BMW E36 Racing Thermostat fits all E36 applications. It 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, allowing the coolant to flow through the engine sooner, which reduces and maintains cooler engine temperatures
