Engine coolant thermostat designed to regulate coolant flow and maintain optimal operating temperature. Ensures efficient warm-up, prevents overheating, and supports reliable performance with a precise fit.
The Mishimoto BMW Racing Thermostat fits all N52, N54, and N55 engines. It will promote greater cooling efficiency throughout your engine. Mishimoto racing thermostats will significantly lower high engine temperature produced by modified and upgraded N52, N54 and N55 engines. Once the engine is fully warmed up the Mishimoto Racing Thermostat will open up at a lower temperature than the stock thermostat, allowing the coolant to flow through the engine sooner thus reducing and maintaining cooler engine temperatures.
- Activates at lower temperature so coolant flows through system earlier
- Allows for cooler engine temperatures
- Mishimoto Lifetime Warranty
