What makes this AEM coil different from a standard ignition coil?

This AEM coil delivers significantly higher spark energy (over 100mJ) and voltage (40,000+ volts) than a typical inductive coil. It also provides a longer spark duration at full energy, which is better for lighting off fuel in modified engines.

Do I need a separate CDI box to use this coil?

No, you do not need a separate capacitive discharge ignition (CDI) box. This coil is designed to provide CDI-like performance on its own, simplifying your ignition setup.

Can I use this coil in California?

No, this AEM High Output Inductive Coil is not CARB approved and cannot be shipped to California due to emissions regulations.

Product Details

Any enthusiast running boost, nitrous or high RPMs is aware of the trade-offs associated with inductive coils versus converting to a capacitive-type discharge ignition system (CDI). While inductive coils deliver a long spark duration, they lack enough energy to light off the combustion chamber of a modified high-performance vehicle. In contrast, CDIs delivers intense energy but with inadequate spark duration, making the proper mixture in the combustion chamber critical for best performance. This tradeoff ends with AEM's High-Output "Dumb" Inductive Coils, the first inductive coils that deliver CDI-like spark energy and voltage, and the long spark duration necessary for vehicles running forced induction and nitrous.AEM's High-Output Inductive Coils each deliver over 100mJ of spark energy and a minimum of 40,000 Volts-as much as most CDI systems, without the need for a CDI module! They also provide very long spark duration at full energy, unlike CDI systems and multiple spark systems which fire off small spark events prior to and after their CDI burst to mimic longer spark duration.High Output Inductive Coil
