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.

MSD Performance Coil Pack for MINI

Before ordering, check whether you need round or flat pin connectors for your MINI's coil pack. The type of pin is determined by the connectors that link the coil to the wiring harness. To check, slide the red locking tab to the right, press down on the tab, and pull the connector off the coil. Examine the pins to see if they are flat or round. Reattach the connector by pushing it back on until it clicks, then slide the red locking tab back to the locked position.

This high-performance coil pack is a popular upgrade among MINI owners looking to enhance their vehicle's performance over the stock coil. The installation requires removing the factory bolts from the old coil and modifying the MSD factory sleeves by drilling out 1/16" to fit the stock bolts.

Kits Include:

  • MSD Coil Pack
  • MSD Wire Set - Red
  • Inductance: 7mH
  • Maximum Voltage: 36,000 Volts
  • Primary Resistance: 0.51 OHMs
  • Secondary Resistance: 12K OHMs
  • Turns Ratio: 77:1

Key Benefits:

  • Upgraded performance over stock coil pack
  • Enhances ignition efficiency and engine performance
  • High voltage output of 36,000 volts for stronger sparks
  • Low primary resistance of 0.51 OHMs for efficient energy transfer
  • High secondary resistance of 12K OHMs for improved performance
  • Durable construction for long-lasting use

The camshaft position sensor is essential for assisting the engine DME by monitoring the camshaft's position. The data from this sensor is key to optimizing ignition timing and ensuring smooth engine performance. Often referred to as the CMP sensor, this component is crucial for the overall functionality of the powertrain. A failing camshaft position sensor can cause a range of issues, including engine stumbling, hesitation during acceleration, power loss, and even starting difficulties or complete failure to start.

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.

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.
