The Mishimoto BMW E36 62 Degree Racing Thermostat is a direct-fit replacement for the stock thermostat in your BMW E36, designed to promote greater cooling efficiency throughout your engine. This thermostat is designed to open at a lower temperature than stock, allowing the coolant to flow through the engine sooner and reduce engine temperatures. The stainless steel housing ensures maximum durability and reliability and the included gasket makes installation a breeze.
