ultramindz Ignition Coil Pack & Spark Plug Kit for Ford 5.4L V8 (2005–2008) — Set of 8, Black-Boot Direct Fit

ultramindz ignition coil pack and spark plug kit is a complete eight-piece replacement designed to restore reliable ignition for Ford 5.4L V8 engines used in 2005–2008 F-150, Expedition, F250/F350 Super Duty, Lincoln Navigator, and Mark LT models.

If your 5.4L Ford or Lincoln has rough idling, misfires, or decreased performance, replacing worn coils and plugs often brings back smooth starting and steadier power delivery. This kit pairs matched ignition coils with compatible spark plugs and replaces OE references such as DG511, UF537, 3L3Z12029BA and SP546 to fit many 2005–2008 5.4L V8 applications. Before ordering, compare the coil boot color on your original parts—this kit fits models with black boots and not the variants with brown boots.

Which vehicles and engine codes does this kit fit?

This replacement set covers a broad range of Ford and Lincoln vehicles equipped with the 5.4L V8 engine produced in the model years listed. It matches several OE part numbers so technicians can cross-reference compatibility during purchase or installation.

• Ford F-150 5.4L (2005–2007 before 12/2007)
• Ford Expedition 5.4L (2005–2008)
• Ford F-250/F-350 Super Duty 5.4L (2005–2008)

How do these coils and plugs replace OE parts and references?

The ultramindz set is manufactured to match fitment and electrical characteristics of the listed OE references so installation follows original mounting points and connector types. Cross-reference numbers provided in the listing help confirm exact compatibility with your vehicle.

• Replaces DG511, UF537, DG-511, FD508, and related OE codes
• Spark plug equivalents include SP546 and factory reference numbers
• Designed for direct swap with original coil pack connectors and boots (black-boot variant)

What should I check before buying or installing this kit?

Verify the color of your existing coil boots and the engine production date to ensure the correct variant. Also plan to have the parts installed by a qualified mechanic to avoid damage from improper handling or torque settings.

• Confirm coil boot color—this kit fits black-booted coils, not brown-boot designs
• Check your vehicle’s build date (some 2007 units vary by production month)
• Have a professional handle installation and torque specifications

What benefits should I expect after replacing coils and plugs?

A matched set of new coils and plugs can reduce misfires, improve throttle response, and enhance fuel combustion consistency without altering engine tuning. While results vary with vehicle condition, fresh ignition components often restore lost drivability and reduce emissions related symptoms.

• Smoother idle and more consistent power delivery
• Reduced risk of misfires and related check-engine lights
• Renewed compatibility with factory ignition timing and control modules

Who is this for: This ultramindz coil pack and spark plug set is intended for owners, mechanics, and fleet operators who maintain 5.4L V8 Ford and Lincoln vehicles from 2005–2008 and need a full eight-cylinder ignition replacement. It’s ideal when troubleshooting recurring misfires, preparing a vehicle for inspection, or restoring performance after long service intervals. If you’re unsure about fitment, consult your service manual or a certified technician before purchasing.
