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.

RACING SPARK PLUG FOR M50/M52/M54 ENGINES
These spark plugs are recommended by BMW Motorsport for use in their DTC racing engines. We find a slight horsepower increase and greatly increased durability over the OEM road car spark plugs in competition use. We attribute the improvements to the fact that these spark plugs are designed for the high temperatures and cylinder pressures encountered in a racing engine. These spark plugs are a direct replacement and come pre-gapped just like the factory road car plugs.
Please note: these plugs are not for the S54 engine in the E46 M3, MZ3, or Z4 M

Sometimes a bad coil may just be a broken or damaged connector boot. This is especially true on cars with a leaking valve cover gasket where the oil has contamintated the rubber boot and the electrical parts inside. This boot can be replaced on its own without having to buy a whole new coil. This part is also useful if you purchased a coil that did not come with a new boot.
