The MSD Smart Coil is a direct replacement for the popular IGN-1A coil. Here's the difference; it produces more spark energy while consuming less power without sacrificing voltage output. This means you get hotter spark at the plug to burn the maximum amount of fuel in each cylinder while using less power from your electrical system.
Features:
More spark energy than any other IGN-1A smart coil on the market for maximum fuel burn during combustion sequence
Low current draw means less demand on the electrical and charging system
Built-in ignitor for compatibility with Holley EFI and many other aftermarket ECU's
Maximum operating voltage of 17 volts - for compatibility with both 12 volt and 16 volt electrical systems found in many performance/race applications
Same wiring pinout as other IGN-1A coils for easy plugin upgrades
Elongated mounting holes to allow direct replacement of IGN-1A coils and will bolt in place of factory LS 1/2/3/6/7 coils with 72mm bolt spacing
Direct bolt-on to Holley cast aluminum LS valve covers with 72mm bolt spacing
