AEM High Output IGBT Inductive "Smart" CoilThe tradeoff between adequate spark energy and adequate spark duration ends with AEM's High Output Inductive Coils, the first inductive coils that deliver CDI like spark energy and voltage, and the long spark duration necessary for vehicles running high compression, high RPM, forced induction and or nitrous engines. Auto enthusiasts who have forced induction engines, high RPM engines or run nitrous oxide are aware of the compromises that come with
