Description

Your BMW’s direct ignition coil provides the power in order for your spark plug to “spark”. If your BMW is suffering from a misfire issue it is likely due to a worn ignition coil or bad spark plug. One way to test for a bad ignition coil is to swap the ignition coils and see if the misfire follows the suspected bad ignition coil.

We also recommend using dielectric grease when installing new ignition coils. It will protect the spark plug boot and create a water/dust tight seal. Great for added ignition performance.
