The N54, N55 and S55 engines are no strangers 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, 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 highly recommended to install the thermostat, especially for cars that are tuned.

THE NEXT LEVEL OF TEMPERATURE CONTROL

A highly recommended upgrade for N54, N55 and S55 engines.

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.

Additionally to the thermostat we have oil cooler kits for the 1-Series E8x and the 3-Series E9x. We advise the Oil Cooler Kit for cars that use the full performance of the car during track use. The kits are available as single or twin cooler kits. The single cooler kit replaces the OEM cooler on the right side of the car, the twin kit will add an extra cooler on the left side of the car.
