This kit bundles eight matching ignition coils and iridium spark plugs engineered to fit many 2008–2014 Ford and Lincoln 4.6L and 5.4L V8 models. Components are built with heat-resistant housings and high-conductivity copper windings, while the iridium plugs use durable electrodes for longer life and consistent spark performance.\u003c\/p\u003e\n\n\u003ch3\u003eWhich vehicles and engines is this kit compatible with?\u003c\/h3\u003e\n\u003cp\u003eThis set is designed for multiple Ford, Lincoln and Mercury V8 models commonly equipped with 4.6L or 5.4L engines from the 2008–2014 model years.
