Dinan Ignition Coil B-Series - Red (Each)

High-output coil pack upgrade for BMW B-series engines - red finish

Give your BMW B-series a sharper, cleaner spark with this premium red coil-on-plug unit. Engineered as a true drop-in swap for the factory module, it delivers up to 10 percent more energy for stronger ignition performance and dependable combustion under load. Ideal as a performance upgrade or a reliable replacement to cure rough idle, hesitation, stuttering or intermittent misfires.

We have fitted these for customers and on our own builds. Feedback has been consistently positive - quicker starts, smoother running and confident pull through the rev range. Looks great under the bonnet too thanks to the red housing.
