Motorcraft-branded spark plugs are manufactured by various companies under contract with Ford Motor Company, which owns the Motorcraft brand. These suppliers often produce spark plugs for other brands as well, but those specifically designated as Motorcraft are engineered to meet Ford’s specifications for its vehicles. This often involves specific design elements like electrode materials and gap sizes, optimized for performance and longevity in Ford engines.
Ensuring the correct spark plug is used in a vehicle contributes significantly to optimal engine function. Using spark plugs designed according to manufacturer specifications can impact fuel efficiency, emissions, and overall engine performance. Historically, Motorcraft components, including spark plugs, were primarily used in Ford vehicles during assembly and servicing. However, the availability of Motorcraft parts in the aftermarket allows owners of various makes and models to benefit from components built to Ford’s exacting standards.
