Holley 556-162 Details

These Holley EFI Smart Coils are a bolt-in ignition upgrade for your late model HEMI 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.

For Hemi combinations currently using Holley EFI or Terminator X, use Smart Coil Ignition Harnesses 558-312 And Coil Extension Harnesses 558-326 for a plug and play solution.
