Do you need require precision control over your ignition system? Or just want to upgrade your stock coil packs? Here at Aeroflow we have the answer with our high output IGN-1A smart coil. This coil delivers similar performance to a CDI system without the need for the bulky and costly CDI control box, as the igniter is built right into each individual coil. They produce more spark energy while consuming less power without sacrificing voltage output. These IGN-1A coils deliver a powerful, long duration spark and are ideal for use in high-boost or high-compression engines. Capable of working with both 12 and 16 volt electrical systems and many aftermarket ECU's makes it the coil pack of choice.
