Ignition

If your engine is throwing a misfire code, there's a good chance the ignition coil is on its way out. Ignition coils are key components in your engine's ignition system, responsible for generating the spark that fuels the combustion process. When they fail, you can experience weak or intermittent sparks, leading to misfires, decreased engine power, and poor overall performance.

If you’re looking to address ignition problems or simply upgrade your setup, consider our High-Performance Ignition Coils! Our ignition coils are engineered to deliver superior spark energy, ensuring smoother, more efficient combustion. Not only will they improve engine performance, but their vibrant blue design and TURNER branding will also give your engine bay a sleek, high-performance look.

Ignition coils should be changed every 40,000 - 60,000 miles and are an important maintenance item due to the essential role they play in your engine's health, performance, and efficiency. Choose Turner Ignition Coils to keep your engine running strong and healthy.

Features & Benefits:

Increased performance! Our performance ignition coils offer a much-needed increase in spark energy, granting your engine a stronger, more consistent spark. Direct plug-and-play upgrade for BMWs equipped with N63B44T3 (N63B), S63B44T4 (S63M), and S68 (S68T). The coil body is finished in our signature "Turner blue" and features a laser-etched, resin-coated Turner insignia. The spark plug boot is constructed from durable rubber and is pre-lubricated with dielectric grease for easy installation. Note: Not all N63B and S63M applications use the same ignition coil. Many S63B44T4/S63M applications—including the F90 M5 and F91/F92/F93 M8—use the older "N Series" ignition coil architecture. If your N63/S63-equipped BMW utilizes the older "pencil style" ignition coil, you can find the Turner Motorsport Performance version HERE.

Our B Series ignition coils are designed with performance and efficiency in mind. An engine needs 3 main components to run (Air, Fuel, Spark.) Ignition coils are responsible for 1/3 the operation your engine and it would be smart to weigh the options when shopping. Turner B Series ignition coils are modified to increase energy output; more energy output results in a faster, more efficient and consistent burn to make sure your fuel is being utilized to its maximum potential. Our signature Turner ignition coils feature a blue housing that give your engine the performance and aesthetic your looking for.

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.
