Enhanced ignition kit for Ford and Lincoln 5.4L V8

The BELKEBIR 8-piece set brings together DG511 and FD508 ignition coils with SP546 iridium spark plugs, designed to revitalize the firing sequence of 5.4L V8 powertrains. This kit targets generations from 2004 through 2008 for models including Expedition, F-150, F-250, F-350, Lincoln Navigator, and Lincoln Mark LT, ensuring a straight black boot configuration compatible with the intended engines.

Engineered to mirror original factory performance, these parts support predictable ignition energy and stable spark across a wide range of temperatures. By restoring the spark-to-piston timing, you may notice smoother idle, more confident starts, and steadier throttle response in everyday driving.

  • Spark plugs: SP546 or SP546X, designed with Iridium electrodes for durability
