AKA the IGN-1A, the ultimate in high performance inductive ignition. Compact single coils from AEM in the USA. The name “smart coil” is given because of the coil’s own inbuilt ignitor. This inbuilt ignitor means that you do not need heavy, lossy low tension wiring from the ECU or coil driver to the coil. The coil instead needs only a +12v feed, earth and a low current trigger from the ECU. The trigger can be +5 to +12v and the coil will discharge on the falling edge of the trigger.
You can use a single coil with a distributor or for the ultimate in spark performance you can use a coil per cylinder.
It is ideal for Adaptronic installations and other ECU’s that output a low current positive ignition trigger.
A great coil for people struggling to maintain spark in a high performace boosted or nitrous powered engine. The closest thing you will get to CDI without the expense and complication.
4 of these coils are used in one of our demonstrater 1/4 mile Renault 5 drag cars – running 2.4 bar of boost pressure and 125hp direct port nitrous oxide. Nothing else could keep the spark alive at those levels, and we tried a lot. Well-known high output wasted spark packs would drop spark where these show not even the slightest hint of missfire.
They are each about the size of 2 decks of playing cards and have a spark-plug style HT terminal (aprox 5mm OD)
Supplied with connector, pins and weather seals.
