Worn ignition coils are one of the most common causes of misfires and sluggish acceleration on BMW B series engines, and replacing them is routine maintenance on any high-mileage or tuned car. The Dinan D655-0001 kit equips a 4-cylinder B-Series engine with Dinan coils that plug straight into the factory connectors and deliver up to 10% more energy than stock for a stronger, more consistent spark. The black housings carry the Dinan logo, adding a visible detail under the hood.
