Boost your B-Series engine’s performance with MMX Performance High-Output Ignition Coils. Designed for an easy plug-and-play upgrade, these coils deliver a stronger, more consistent spark by providing a 10% increase in energy output compared to your OE factory coils. Perfect for both stock and tuned engines, this upgrade ensures better throttle response, improved fuel efficiency, and optimized ignition performance for your BMW.

Every MMX coil pack is engineered to transform your car battery’s 12-volt output into a more powerful voltage, enhancing the spark plug’s reliability to ignite the air-fuel mixture efficiently. With meticulous development to optimize energy levels, MMX coils feature excellent thermal management, which helps maintain consistent performance while reducing the risk of breakdown over time. This makes them an ideal preventative maintenance upgrade for older engines still running on their original coils, reducing the chance of misfires as your OE coil packs age.

Our B-Series coil packs are fully compatible with the BMW B36, B38, B46, B48, B58, and S58 engines, with fitment as easy as removing the old coils and replacing them with MMX’s higher output versions—no modifications required. Available in red, grey, and blue finishes, they not only enhance your engine’s performance but also add a stylish touch. For optimal installation and longevity, we recommend applying dielectric grease around the rubber boot. Compatible OEM part references include 12138643360, 12137619385, 12138678438, and 750990012, making these a simple and effective upgrade to bring out the best in your BMW.
