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.

MINI B46 B48 Spark Plug is an essential component for maintaining the optimal performance of your engine. When spark plugs become worn, symptoms such as poor idle, reduced fuel efficiency, and engine misfire codes may arise. These issues are often caused by excessive carbon build-up and a worn electrode, which can affect the spark plug's ability to ignite the fuel-air mixture effectively. Replacing your spark plugs regularly as part of routine maintenance ensures that your engine continues to run smoothly.

Manufactured by Bosch, an Original Equipment Supplier (OES), these spark plugs are designed to meet the exact specifications of your MINI, ensuring reliable ignition performance and long-lasting durability.

• Improves engine performance: Reduces issues like poor idle, low fuel efficiency, and engine misfires.
• High-quality construction: Made by Bosch, an OES supplier, ensuring OEM quality and reliability.
• Prevents carbon build-up: Regular replacement helps avoid excessive carbon deposits and electrode wear.

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.
