Upgrade your late model HEMI or Coyote engine's ignition system with these Holley EFI Smart Coils. The key differentiator from stock coils lies in their ability to generate more spark energy while consuming less power. This results in a hotter spark at the plug, ensuring optimal fuel combustion in each cylinder while placing less demand on your electrical system.
For Coyote or Hemi setups currently utilizing Holley EFI or Terminator X, opt for the Smart Coil Ignition Harnesses 558-312 and Coil Extension Harnesses 558-326 for a straightforward plug-and-play solution.
For new Holley EFI installations on Coyote engines, pair these coils with the Holley EFI Coyote TI-VCT Main Harness for Smart Coils 558-122 and Smart Coil Ignition Harness 558-312 for an effortless plug-and-play integration.
