BMW Engine Parts for BMW 6 Series E64 (2004-2010)

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. Sometimes 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.

This is the current replacement for some BMW 6 and 8-cylinder engines built in the late 2000s and after. BMW has made numerous changes to ignition coil part numbers in recent years but has approved this part number to work in the vehicles listed below. It's listed as a replacement coil for N20, N55, and S55 engines. In March 2015 BMW approved it for N51/N52 engines. This part number replaces the previous BMW part number 12137594937 for the cars listed below.

Sold per coil. Includes boot and connector.

Perfect for DIY enthusiasts, this all-in-one kit has everything you need to refresh your ignition system! With just one click, you'll get high-quality, matching replacement parts, making it simpler than ever to service and restore your ignition system.

If you're noticing misfires, poor fuel economy, reduced engine performance, or ignition-related diagnostic trouble codes (DTCs), a failing ignition coil is likely the cause. Late-model BMWs, such as the E60 M5, E63 M6, and E64 M6, use a coil-on-plug ignition system, where each cylinder has its own coil and spark plug for efficient ignition. When a coil fails, the affected cylinder won't receive a spark and will misfire. Even if the misfire doesn’t trigger a DTC, you’ll still feel the difference in engine performance—rough idling, hesitation during acceleration, or a strong fuel smell. To avoid these issues, we recommend replacing your ignition coils every 40,000-60,000 miles.

The S85's MSS65 DME uses a unique ignition system known as Ionic Current Control. BMW engineers developed this system to more accurately detect pre-ignition and misfires in the high-revving, ten-cylinder S85. Instead of relying on conventional knock sensors, the system uses each spark plug as a current probe, applying a low voltage to the electrode immediately after the power stroke and sending the resulting current to the Ionic Current Control Unit (ISS) for evaluation. This allows for precise monitoring of combustion events. To support this, the S85’s ignition coils are specially designed with a modified “pencil” shape and lack the typical Zener diode in the secondary winding, allowing for accurate current measurements without triggering fault codes in the engine control unit (DME). Bavarian Autosport ignition coils are manufactured to the exact specifications of the OE Ionic Current Control-compatible ignition coils, and will not trigger ignition-related fault codes in the DME.

Bavarian Autosport ignition coils are engineered for reliability, delivering a consistent, long-lasting spark. These high-quality OE replacement coils are specifically designed for your S85-powered E60 M5, E63 M6, or E64 M6. Constructed with durable, heat-resistant plastic and featuring premium rubber spark plug boots, each boot is pre-lubricated with dielectric grease to ensure smooth installation and prevent corrosion.

A common source of oil leaks is the valve cover, where gaskets can degrade over time due to extreme temperature fluctuations. Replacing these gaskets is essential to prevent leaks and ensure your engine runs smoothly.

Maintaining proper oil levels is critical for engine performance. Unnoticed leaks can cause oil levels to drop dangerously low between changes, risking severe engine damage.

What's Included in the Kit:

Valve Cover Perimeter Gaskets NRW Design Silicone Grommets/Sealing Washers (x30) Assorted O-Rings, Screws, and Necessary Hardware Replace your valve cover gaskets with our comprehensive kit to maintain optimal oil levels and protect your engine from damage.
