The BMW S55 N54, N55 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.
A highly recommended upgrade, the Mosselman Oil Thermostat is plug-and-play and made out of a solid block of high-grade aluminum at our own facility. It is equipped with a real thermostat, not an always open solution. The oil will still reach the operating temperature at the same time as a stock thermostat.
Note: The Oil Thermostat Installation kit prevents the thermostat from leaking and is highly recommended when installing the Mosselman Oil Thermostat. The kit includes 2 x O-ring for the oil hose and 1x rubber oil filter housing gasket. We advise you to add it to your order.
