When an ignition coil begins to fail, your GM vehicle may misfire, idle roughly, hesitate under load, or trigger a check engine light. Replacing worn ignition components with genuine GM parts helps restore the system your engine was built to use. At Gateway Parts Online, Chevrolet, GMC, and Buick owners can shop OEM ignition coil parts online and use vehicle fitment tools to narrow results before ordering.
What This Category Includes
- Genuine GM ignition coil assemblies for compatible engines and model years.
- Ignition Coil Wire options for applications that use separate coil-to-plug connections.
- Ignition Coil Spacer parts and mounting-related components where required by the factory design.
- Related ignition system parts, including spark plugs and glow plugs, modules, and electrical connectors when applicable.
Why Genuine GM OEM Parts Matter
Ignition parts work in a demanding environment with heat, vibration, and constant electrical load. Genuine GM OEM components are designed to match the factory specifications of your vehicle, helping support correct spark energy, connector fit, mounting position, and engine control communication. Aftermarket coils may look similar, but small differences can affect fitment, drivability, or long-term reliability.
How to Choose the Right Part
Start with your year, make, model, engine size, and drivetrain. Then compare the part notes for cylinder position, production date, engine RPO, and included hardware. If you are replacing one failed coil, inspect the surrounding boots, wires, and spark plugs at the same time. For best results, follow the service information and consult your Owner's Manual before beginning ignition system work.
GM Fitment Guidance: VIN + Trims
GM fitment can vary by trim, engine, emissions package, and production change. A Silverado, Sierra, Enclave, Traverse, Acadia, or Terrain may use different ignition coil parts depending on engine family and build details. Use your VIN whenever possible to confirm compatibility before checkout, especially if your vehicle has multiple engine options within the same model year.

Should I replace all ignition coils at once?
It depends on mileage, engine condition, and service history. Some owners replace only the failed coil, while others replace coils in sets to reduce repeat labor.
Do I need my VIN to order an ignition coil?
Using your VIN is strongly recommended because GM fitment may vary by trim, engine, production date, and option package.
