3… 2… 1… Ignition!

The ignition coils used on most cars today haven’t changed all that much in the last 50 years. A simple set of windings that when provided electricity creates a magnetic field that when collapses is amplified and creates enough voltage potential that it can jump a gap between two points. For our purpose with this article that’s as far as we’ll go with the understanding of transformer (ignition coil) fundamentals. Let’s instead focus on the bigger picture as it relates to misfires, specifically those that occur from increase boost and power development.
