Description

The Mishimoto BMW Racing Thermostat is engineered for the 1999-2006 BMW E46 323i, 325i, 328i, and 330i. This thermostat fits all M52, M54, and M56 engines, promoting greater cooling efficiency. It lowers high engine temperatures in modified and upgraded engines by opening at a lower temperature than the stock thermostat. This allows coolant to flow through the engine sooner, reducing and maintaining cooler engine temperatures for improved long-term reliability of cooling components.
