What makes coil packs go bad?
Excessive heat and vibration can cause the insulating material to break down and create internal coil failure. Worn secondary ignition components such as spark plugs or wires can cause a coil work harder, require more voltage, and therefore significantly reduce the operating life of the coil.
What will cause an ignition coil to fail?
The overheating of ignition coils can hinder their ability to conduct electricity. Wear and tear is a common reason for ignition coils failing. It causes degrading of the insulation between the primary and secondary coil windings and the primary coil. The reduction in insulation can cause the coil to overheat.
Why do coils fail on a Honda?
As for the Honda, more likely there's something else at work causing coil failures as a symptom of another problem. Nissan V6's had an issue that would cause the coils to fail rapidly one after another, it was a broken or poor ground on the engine. Other things that cause coils to fail can be bad connections at the harness, oil or water in the plug tubes, or excessively worn plugs putting a high spark energy demand on the coils.

What is an ignition coil?
by David Dunning. The ignition coil is the heart of an automotive spark ignition system, but is essentially just an electrical transformer. It consists of a primary coil made up of 100 to 150 turns of heavy copper wire and a secondary coil made up of 15,000 to 30,000 turns of fine copper wire.
