AEM’s new CDI Pencil Coils are now available! Easily allowing the conversion to coil-on-plug ignition systems, these Pencil Coils will work with aftermarket engine-management systems. Additionally, when Pencil Coils are used in high-boost, high-RPM, or high-compression applications, an increase in spark energy can be seen over factory smart coils.
anyone running these on there car ? anything noticeable ? and what the heck is a cdi ignition module ?
