Show original supplier description

The Motorcraft SP-548 spark plug is engineered by Ford to meet specific engine requirements, ensuring enhanced durability, reduced misfires, and improved fuel efficiency to comply with emission standards. It features a nickel-plated shell that provides superior corrosion resistance and a refined appearance. This spark plug is compatible with Ford F-150 models from 2011-2017 equipped with the 5.0L V8 Flex engine. It also fits Ford Mustang models from 2011-2020 with either the 5.0L V8 Gas engine or the 5.2L V8 Gas engine (without supercharger on the 5.2L). Specifically, it is listed for 2015-2017 F-150 models (excluding Raptor) and 2015-2020 Mustang models, including the Shelby GT350 and GT350R. Motorcraft is the genuine parts brand from Ford, ensuring that these spark plugs are the same quality and specifications as the original equipment installed on the assembly line. Replacing your spark plugs at recommended intervals is crucial for maintaining optimal engine performance, fuel economy, and smooth operation.
