Black, 8-PackDirect bolt-on to factory valve coversSame wiring pinout as other IGN-1A coils for easy plugin upgrades (Will not work with factory wiring)More spark energy than any other smart coil on the market for maximum fuel burn during combustion sequenceLow current draw means less demand on the electrical and charging systemBuilt-in ignitor for compatibility with Holley EFI and many other aftermarket ECUâ??sMaximum operating voltage of 18 volts â?? for compatibility with both 12 volt and 16 volt electrical systems found in many performance/race applicationsThese 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.For Coyote or Hemi combinations currently using Holley EFI or Terminator X, use Smart Coil Ignition Harnesses 558-312 Coil Extension Harnesses 558-326 for a plug and play solution.For new Holley EFI installations on Coyote engines, use with Holley EFI Coyote TI-VCT Main Harness for Smart Coils 558-122 Smart Coil Ignition Harness 558-312 for a plug and play solution.
