The Link IGN-1A Smart Coil is a high-output inductive ignition coil with a built-in ignitor, delivering 103 mJ of spark energy and a long 2.9 ms spark duration. Designed for universal ignition systems, it provides reliable, high-energy ignition for naturally aspirated, turbocharged and supercharged engines without requiring an external ignitor.
