Mosselman - Oil Thermostat || N55 (F-Gen ONLY)

The N55 engine is no stranger to oil cooling problems, that’s why we recommend installing the Mosselman Oil Thermostat. The standard oil thermostat will reach around 120 degrees Celsius with a normal driving style. The Mosselman Oil Thermostat will open at a lower temperature than the standard oil thermostat (at 185 degrees Fahrenheit) and will keep the temperature stable between 203 and 221 degrees Celsius, depending on the car model. 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.

The 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.
