These Holley EFI Smart Coils are a bolt-in ignition upgrade for your late model HEMI or Coyote engine. Here's the difference over a stock coil; they produce 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.
