Product InformationOEM replacement direct ignition coilYour 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 misfire.
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.
Note: This newly designed Bosch coil does not have a "snap" when pressing into place. The new design uses a contact spring on the spark plug tip that grips the spark plug just as good or better than the original design. When installing a new coil make sure each spark plug connector has a dab of dielectric grease to make sure the coil slips all the way down on to the plug and are firmly in place.
Direct Ignition CoilDirect ignition coils are located directly over the top of the spark plug. In this ignition setup there is one ignition coil per spark plug and there are no spark plug wires. This ignition setup is often referred to as a coil on plug ignition system.
Coil on plug or direct ignition systems are pretty much used on all modern cars due to packaging, performance, emissions, and maintenance reasons. This ignition system is essentially maintenance free with the exception of spark plug replacements and the occasional coil replacement when compared to a traditional ignition system.
