COIL PACK

Classic Ford - - CFTECH -

Con­ven­tional sys­tems use one coil, but here it’s re­placed by the coil pack, fea­tur­ing two coils di­rectly con­nected to the HT leads and sub­se­quently, the plugs.The rea­son for the dual coils is be­cause the sys­tem is known as wasted spark. With man­aged ig­ni­tion, the sys­tem has no way of telling whether the en­gine is on its com­pres­sion or ex­haust stroke. So, the coil pack is used not only to pro­vide slightly more charg­ing time but also to fire the spark on both en­gine strokes — the one on the ex­haust stroke is wasted — hence the name.
