Ford typically uses Motorcraft spark plugs as the factory-installed option on most of its vehicles. The exact type depends on the engine family, model year, and regional specifications.
Ford's OEM supplier for spark plugs
Ford orders spark plugs from Motorcraft, the automaker’s own parts division. The Motorcraft line includes several designs—Iridium IX, Double Platinum, and Copper Core—that are matched to specific Ford engines. The precise plug type your vehicle requires is determined by the engine and year.
- Iridium IX spark plugs — designed for long life and robust performance in many modern Ford engines.
- Double Platinum spark plugs — used on some Ford engines, often where long life and reliable performance are needed but Iridium isn’t specified.
- Copper Core spark plugs — traditional design used on older Ford engines or certain specifications requiring a copper core.
In practical terms, most contemporary Ford engines ship with Motorcraft Iridium IX or Double Platinum plugs, while older powertrains may use Copper Core variants. Always verify the exact specification for your model and year with official resources.
How to identify the exact Ford spark plug for your vehicle
To ensure you install the correct OEM plug, follow these steps:
- Identify your vehicle’s exact engine code and model year, since Ford engines have multiple variants.
- Consult the owner's manual or the Ford service manual for the recommended Motorcraft plug type and the proper gap specification.
- Use FordParts.com or the Motorcraft catalog with your engine code or VIN to pull the precise OEM spark plug part number.
- Compare options (Iridium IX, Double Platinum, Copper Core) and confirm the recommended replacement interval for your engine and driving conditions.
- Purchase genuine Motorcraft plugs from a Ford dealer or authorized retailer to ensure compatibility and warranty coverage.
By following these steps, you can be confident you’re using the OEM spark plugs Ford designed for your vehicle.
