Overview

Unlike the OEM thermostat which operates around 120 degrees Celsius, this Mosselman unit opens at a lower temperature of 85 degrees Celsius. This results in a stable operating temperature between 95 and 105 degrees Celsius, depending on the vehicle model.
Show original supplier description
The Mosselman Oil Thermostat is a highly recommended upgrade for BMW N54 engines, addressing common oil cooling issues. The standard oil thermostat typically reaches around 120 degrees Celsius during normal driving. This Mosselman unit features a thermostat that opens at 85 degrees Celsius, maintaining a stable oil temperature between 95-105 degrees Celsius, which improves engine performance stability and reliability, especially for tuned vehicles. Constructed from a solid block of high-grade aluminum at Mosselman's facility, this thermostat is designed as a plug-and-play solution. It functions as a real thermostat, suitable for both hot and cold climates, ensuring the oil reaches its optimal operating temperature effectively. The product number for this unit is 030210050. Installation is straightforward, taking approximately 30 minutes. For optimal installation and to prevent leaks, Mosselman highly recommends the accompanying Oil Thermostat Installation kit, which includes essential O-rings and a gasket.
