A high-performance BMW oil system is essential for maintaining optimal engine temperature, lubrication, and longevity, especially under high-performance and track conditions. Common issues such as oil overheating, pressure drops, leaks, and sludge buildup can lead to engine wear, reduced efficiency, and potential failure. Upgrading to high-performance BMW oil system components, including high-capacity oil coolers housing, thermostats, or low oil temperature kits ensures superior oil cooling, improved lubrication, and reduced engine heat soak. These upgrades help prevent oil starvation in high-G turns, minimize sludge accumulation, and enhance overall engine durability and performance. Whether pushing your BMW on the track or ensuring long-term reliability for daily driving, Turner Motorsport offers premium OEM and performance BMW oil system components to keep your engine running at peak efficiency.

The N54 engine is no stranger 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. 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.
