Description

The Motorcraft SP-479-X is a premium platinum spark plug, featuring a copper core for enhanced conductivity and durability. This plug is engineered with a 14mm thread size and a 26mm reach, complemented by a tapered seat to ensure a precise and secure fit within the cylinder head. Designed for optimal performance, the SP-479-X operates within a heat range of 6, suitable for a variety of engine conditions. It comes with a preset gap of 0.054 inches, simplifying installation and ensuring it meets factory specifications for many Ford applications. The 5/8 inch hex size allows for straightforward tool engagement during replacement. Fitment information indicates this spark plug is designed for specific Ford vehicles, including the E-250 (2005-2008), E-450 (2008), Excursion (2000-2005), and Expedition (1998-2004). It is also noted as being suitable for Ford 4.6L 2-valve engines and 5.4L/6.8L SOHC engines. However, it is explicitly stated that this part does not fit the 2024 Ford Explorer Base 2.3L L4 - Gas model.
