Holley EFI Smart Coils are a bolt-in ignition upgrade for your late-model Ford Coyote or Mopar Gen III Hemi engine. Compared to a stock coil, they produce more spark energy while consuming less power without sacrificing voltage output. This means you get a hotter spark at the plug to burn the maximum amount of fuel in each cylinder while using less power from your electrical system. For more information, visit www.holley.com.
