Mosselman Oil Thermostat BMW M2 N55 F87

The N55 engine is no stranger to oil overheating problems; the standard oil thermostat will reach around 120°C with a normal driving style.

The Mosselman oil thermostat opens at a lower temperature than the standard oil thermostat (85°C ) and keeps the temperature stable between 95 and 105 °C, depending on the car model. Installing the MSL thermostat ensures a cooler oil temperature, which results in more consistent performance and, above all, improved engine reliability. Installing the thermostat is recommended, especially for cars with remapped ECUs and/or used on track.

The oil will still reach operating temperature in the same time as with a standard thermostat.

Team Lupos tip:

"The oil thermostat installation kit prevents the thermostat from leaking and is strongly recommended when installing the Mosselman oil thermostat. The kit includes 2 O-rings for the oil pipe and 1 rubber seal for the oil filter housing."
