Mercury Marine IGN Dumb Coil

The Mercury Marine IGN “Dumb” Inductive Coil is designed to be used with an external igniter. Works great in conjunction with the Haltech HPI ignition modules! WHAT IT DOES The IGN “Dumb” Inductive Coils each deliver up to 118mJ of spark energy and a minimum of 41,000 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 its CDI burst to mimic longer spark duration. The full energy delivery and long duration of the High-Output Inductive Coils eliminate the need to compromise energy or duration with your ignition system, and will increase performance in high-boost or high compression engines. WHY YOU WANT ONE The High-Output “Dumb” Inductive Coils deliver CDI-like spark energy with the long duration of an inductive coil, and easily install in place of your exiting coils without the need to add a CDI.
