Product Information

Eldor manufactured coil number 12138657273

Your BMW's direct ignition coil contributes the power in order for your spark plugs to "spark". If your BMW is having a misfire issue it is likely due to a worn ignition coil or bad spark plug. One way of testing for a bad ignition coil is to swap out the ignition coils and see if the misfire follows the misfire.

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

Direct Ignition Coil

Direct 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 bascially 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.

A small upgrade from the stock coils for my 07 335i. Definitely helps with the misfires from the boost in hp from my stage 2 tune with MHD
