AEM Coil-On-Plug Pencil Coils
AEM CDI Pencil Coils (when used with an AEM Twin Fire ignition amplifier or aftermarket ignition amplifier) can replace the factory coil-on-plug smart coils, or can be combined with a CDI module, AEM Engine Position Module and a standalone engine management system to convert a vehicle's distributed ignition system to coil on plug. When used with an aftermarket CDI, AEM Pencil Coils can show an increase in spark energy over factory smart coils. These coils are 2-wire CDI compatible and ideal for use in high-boost, high-RPM, or high-compression engines.
What are the reasons to convert to a coil-on-plug setup?
AEM's CDI Pencil Coils allow you to convert to a coil-on-plug ignition system or replace your smart coils to increase the spark energy delivered into your combustion chamber. If you have a high boost, high RPM or high compression engine, your ignition system may not be powerful enough to produce a full spark. AEM's pencil coils are one of the critical components to provide your engine the spark it needs to produce the most power.
