IGN-1A Smart Coils (set of 4)


Categories: , ,


Designed for two-stroke marine engines requiring lots of spark, these coils can not be beat for the rotary!  Rotary and two-stroke motors behave very similarly with twice the ignition events per revolution compared to a standard 4 stroke motor (which more coils are designed for).

**SET OF 4**

CDI-Level spark energy without a CDI make these IGN-1A Ignition Coils a must for boosted, high RPM, high compression and nitrous-equipped vehicles! The tradeoff between adequate spark energy and adequate spark duration ends with High-Output Inductive Coils, the first inductive coils that deliver CDI-like spark energy and voltage, and a long spark duration necessary for vehicles running high compression, high rpm, forced induction and/or nitrous engines.

IGN-1A  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 direction.

IGN-1A  High-Output coils easily install in place of your existing coils. They are constructed to operate in harsh environments and are shock and weatherproof allowing them to be mounted virtually anywhere. The High Output coils cost less than the cost of aftermarket LS1 coils and deliver World Class performance. They are currently running on 2,000 horsepower nitrous motors without a CDI, and the perform flawlessly.
