Inductive Smart Coil, Spark Energy up to 118 mJ! 1978-chevrolet-monte-carlo-esi8544371 Bolt - 5/16-18 in ThreadAEM'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.
