If you drive a GM or Ford vehicle, ACDelco and Motorcraft are the factory-recommended spark plug brands. But how do they compare if you're cross-shopping or considering alternatives?
ACDelco: GM's OEM Supplier
ACDelco is the parts division of General Motors. Their Professional Iridium plugs are engineered specifically for GM's EcoTec3, EcoTec, and LSX family of engines. If you own a Chevy, GMC, Buick, or Cadillac, ACDelco plugs are the factory spec.
ACDelco's iridium plugs offer 100,000-mile service intervals on most GM applications. They're well-made and maintain tight factory tolerances throughout their service life.
Motorcraft: Ford's OEM Supplier
Motorcraft is Ford's parts brand, and their spark plugs are designed for Ford's Coyote, EcoBoost, and Modular engine families. Motorcraft plugs are engineered to work with Ford's specific ignition timing maps and combustion chamber geometry.
For any Ford vehicle, Motorcraft plugs are the no-compromise OEM choice. They provide reliable performance and the 60,000-mile (iridium) or 100,000-mile service intervals Ford recommends.
Can You Mix Brands?
While NGK or Champion plugs often fit GM and Ford engines, sticking with OEM brands (ACDelco for GM, Motorcraft for Ford) ensures you're getting plugs that were specifically calibrated for your engine's tune and ignition system. For most drivers, OEM is the safest bet.
