Mosselman Oil Thermostat
The next level of temperature control
The BMW N54, N55, and S55 engines are no strangers to oil cooling problems, that’s why we recommend installing the Mosselman Oil Thermostat. Instead of opening at 105°C (220°F), the Mosselman Oil Thermostat opens at 85°C (185°F) which results in an operational oil temperature 20°C (68°F) lower than OEM. *Exact temperatures can differ slightly depending on the engine type.
Installing the Mosselman Oil Thermostat ensures a cooler oil temperature which will result in more stable performance, but above all this improves the reliability of the engine. A highly recommended upgrade for the N54, N55, and S55 engines, especially when they’re tuned.
