Holley EFI Gen III Hemi Smart Coils
Holley EFI Smart Coils are a bolt-in ignition upgrade for your Gen III 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. The Smart Coils are available individually and in sets of 8.
* 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.
Features:
* Direct bolt-on to factory valve covers
* Same wiring pinout as other IGN-1A coils for easy plug-in upgrades (Will not work with factory wiring)
* More spark energy than any other smart coil on the market for maximum fuel burn during combustion sequence
* Low current draw means less demand on the electrical and charging system
* Built-in ignitor for compatibility with Holley EFI and many other aftermarket ECUs
* Maximum operating voltage of 18 V—for compatibility with both 12 V and 16 V electrical systems found in many performance/race applications
