Turner Motorsport has everything you need to upgrade your BMW through our stages of performance or to keep your car in peak condition with our range of the latest in proven OEM cooling parts. Upgrade your cooling system and engine performance with the selections below to give your BMW a performance and reliability advantage.
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.

Ignition coils are key to the efficiency and performance of your BMW. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors). Problems with one or more coils will cause a fault code, but not always a check engine light. A misfire code may be related to an ignition coil, but could be from other things as well. ometimes, a visual inspection of a coil and coil boot will give an indication of a failure. You can also move coils around to different cylinder banks to see if the misfire code follows a suspect coil. We suggest always having one or two coils on hand to keep as spares.

The camshaft position sensor communicates the position of the camshaft to the computer. This helps the computer to calculate proper spark and fuel control. If you're struggling with CELs, hard starts or no starts, stalling, and/or a rough idle, you may need to replace the cam position sensor.
