Description
Upgrade your BMW or MINI’s ignition system with the MMX Performance B-Series High Performance Ignition Coils — a plug-and-play solution that delivers a stronger, more consistent spark and a 10% increase in output energy over OEM coils. Whether your engine is stock or tuned, these coils are designed to improve ignition performance, enhance combustion efficiency, and support both reliability and power delivery.
Each coil is engineered to transform the standard 12V supply from the car’s battery into the high-voltage pulse required to ignite the air-fuel mixture effectively, ensuring a smoother idle, improved throttle response, and reduced misfires under load — especially important on high-mileage or modified engines.
MMX’s B-Series coil packs are developed with precise energy control and thermal management to prevent breakdown under heat stress, ensuring durability across the product’s lifecycle. These coils are also a highly recommended preventative maintenance upgrade, especially for aging vehicles still running OE packs that may be prone to failure.
Compatible with factory connectors and ignition systems, these coils are a simple, fast, and effective performance upgrade. They are available in red, grey, or blue finishes to suit your under-bonnet styling.
