Holley's Coyote Smart Coils are a bolt-in ignition upgrade for late-model Coyote engines running Holley EFI or Terminator X. They produce more spark energy than a stock coil while drawing less current, delivering a hotter spark at the plug to burn more fuel per cylinder without taxing the electrical system.
Specifications:
- Category: Ignition Coil
- Configuration: 8-Pack
- Color: Black
- Maximum Operating Voltage: 18 volts (compatible with 12V and 16V electrical systems)
- Connector Pinout: Same as other IGN-1A coils (will not work with factory wiring)
- Mounting: Direct bolt-on to factory valve covers
- Part Number: 556-161
For new Holley EFI installations on Coyote engines, pair these coils with the Coyote TI-VCT Main Harness for Smart Coils (558-122) and Smart Coil Ignition Harness (558-312) for a plug-and-play install. For Coyote or Hemi combinations already running Holley EFI or Terminator X, use Smart Coil Ignition Harness 558-312 and Coil Extension Harness 558-326.
FAQ
What is the benefit of these Smart Coils over a stock Coyote coil?
They generate more spark energy while consuming less current than the factory coil, producing a hotter spark for more complete combustion without added load on the charging system.
Will these work with my factory ignition wiring?
No. They share the same pinout as other IGN-1A-style coils, but factory wiring will not plug directly into them. New installs should use the Coyote TI-VCT Main Harness (558-122) with the Smart Coil Ignition Harness (558-312).
What ECUs are these coils compatible with?
They have a built-in ignitor, making them compatible with Holley EFI, Terminator X, and many other aftermarket ECUs.
How many coils are included in this kit?
This is an 8-pack, covering a full V8 Coyote application.
