MSD - Universal - Use with Holley or MSD EFI Systems 5 in Flange - 7The 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.
