Oil Cooler

BMWs use an external oil cooler to regulate the temperature of engine oil and prevent a breakdown in viscosity and lubrication characteristics. If yours has suffered damage or developed a slight leak, make sure to replace it and keep the engine oil where it is supposed to be. Keeping this system properly serviced will significantly improve performance and increase engine life.

The N54 engine is no stranger to oil cooling problems, that’s why we recommend installing the MSL Oil Thermostat. The standard oil thermostat will reach around 120 degrees Celsius with a normal driving style. The MSL Oil Thermostat will open at a lower temperature than the standard oil thermostat (at 85 degrees Celsius) and will keep the temperature stable between 95 and 105 degrees Celsius. Installing the MSL thermostat ensures a cooler oil temperature which will result in more stable performance, but above all this improves the reliability of the engine. It is recommended to install the thermostat, especially for cars that are tuned.
