Upgrade or replace the factory ignition coil with the Dinan B Series Style Ignition Coil in black. Dinan designed these coils as direct plug-and-play replacements or upgrades, with up to 10% more energy output than stock for a stronger, more consistent spark.

The B Series Style coil applies to BMW and related applications using B36, B38, B46, B48, B58 and S58 engines. The black housing carries the Dinan logo and is intended as a functional ignition upgrade rather than a cosmetic-only part.

Dinan lists compatible OEM cross-reference numbers 12138643360, 12137619385, 12138678438 and 750990012. This is a single ignition coil with mounting hardware included and a manufacturer limited 1-year warranty.
