A High Output Coil With No External Igniter Required
This is the Haltech LS1 coil with a built-in ignitor, a high output inductive coil originally found on most General Motors LS1 Gen 3 engines and widely used in aftermarket ignition setups. Because the igniter module is built into the coil, it can be wired directly to a compatible ECU without needing an external igniter box such as an X4 or X6.
Key Features
- High output inductive coil with a built-in igniter module.
- Wires directly to a compatible engine management ECU, no external igniter required.
- Can draw up to 10A during operation.
- Requires a spark plug lead connection with a ferrule for correct operation.
- Includes a matching plug and pins.
Fitment
| Application | Requirements |
|---|---|
| GM LS1 Gen 3 engine ignition swaps or any application using an LS1-style coil | Requires a spark plug lead with the correct ferrule connection to avoid spark arcing to the coil mount body |

FAQ
Does this coil need an external igniter box?
No, the igniter is built into the coil, so it can be wired directly to a compatible ECU.
What spark plug lead is required?
A spark plug lead connection with a ferrule. Without the correct connection, the spark can arc to the coil mount body near the spark discharge post.
What vehicles originally used this coil?
Most General Motors LS1 Gen 3 engines.
How much current can this coil draw?
Up to 10A.
Is a plug and pins included?
Yes, a matching plug and pins are included.
Where should the coil grounds connect?
Ground Pin A should go to the cylinder head as the return path for spark, and Ground Pin B should go to the ECU signal ground as a reference for the ECU ignition output.
Can this coil be used outside of LS1 applications?
Yes, it is commonly used in aftermarket ignition builds beyond its original LS1 application, provided wiring and dwell settings are configured correctly.
Does this coil have emissions considerations?
Yes, review the applicable emissions notice for your state or region before installing this coil on a road-going vehicle.
Installation Instructions
- Mount the coil in a location with adequate clearance and heat dissipation.
- Connect the included plug and pins, wiring Ground Pin A to the cylinder head and Ground Pin B to the ECU signal ground.
- Connect the ECU ignition trigger output per your engine management wiring documentation.
- Install the spark plug lead using the correct ferrule connection to prevent spark arcing.
- Configure ignition edge and dwell settings in the ECU software to match this coil's requirements.
- Verify spark and ignition timing operation before normal use.

Ignition Coils
Ignition coils take 12 volts from the battery and step it up to the 30,000 to 60,000 volts your spark plugs need to fire under compression. When a coil weakens, the cylinder it feeds misfires under load, throws a P0301 through P0308 code, and drags fuel economy down. This collection stocks direct-fit OEM replacements and high-output performance coils for domestic, import, and JDM platforms. Every coil here comes from a name the shop trusts. Granatelli Pro Series 60KV, MSD Blaster and Xtreme COP, aFe SCORCHER, Mishimoto Race Series, Cusco Type-2, HKS Super Fire Racing Coil Pro, and OE-quality Motorcraft, ACDelco, and Denso units, matched by year, engine, and coil style. Coil-on-Plug, Coil Packs, and Cassette Coils Modern engines run one of three ignition-coil layouts. Coil-on-plug (COP) mounts a dedicated coil on top of every plug, which is what you find on most trucks and performance cars built after roughly 2005. Coil pack systems drive two or four plugs from a single unit, co...
