ENA 8-Pack Ignition Coil and Platinum Spark Plug Set for 5.4L V8 (2005–2008) — Black Straight Boots, Plug-and-Play

ENA's kit includes eight black-boot ignition coils and eight platinum-tip spark plugs designed to replace the factory 5.4L V8 ignition components on select 2005–2008 Ford and Lincoln vehicles.

This complete ignition set is built as a direct-replacement solution for owners of Ford F-150, F-250, F-350, Expedition, Lincoln Navigator and Mark LT models equipped with the 5.4L V8 (2004–2008 model years as noted). The package bundles eight bolt-on coil packs with straight black boots plus eight platinum spark plugs sized and gapped to fit the factory cylinder heads. Before ordering, verify your vehicle uses coils with black straight boots—not brown or curved boots—and confirm engine compatibility through your VIN or the vehicle fitment tool.
