ultramindz Ignition Coil & Spark Plug Kit for Ford 5.4L V8 — 8-Pack DG508 Replacement, Complete Bank

Complete eight-pack ignition coil and spark plug kit engineered to replace DG508-series coils and SP479 plugs for Ford 5.4L V8 engines and select 4.6L applications.

This kit from ultramindz contains eight ignition coil packs and eight matched spark plugs designed to restore ignition efficiency for many Ford trucks, SUVs, vans, and select Lincoln/MV-1 models from the late 1990s through the mid-2010s. It’s intended as a direct replacement for specified OEM part numbers and covers a wide range of chassis where the DG508 coil family is specified. Note: this kit does not fit 2004+ F-150 5.4L vehicles that require the DG511 coil.

Which vehicles will these coils and plugs fit?

These ignition coils and spark plugs fit numerous Ford and related models equipped with the 5.4L V8 (and certain 4.6L) engines when the DG508 family is specified. Coverage includes F-150s, Expeditions, Super Duty trucks, E-series vans, Excursion, Lincoln Navigator, and the VPG MV-1 where listed.

• Covers Ford F-150 5.4L V8 (1998–2003) and F-150 Heritage 2004 with DG508-type coils.
• Includes Expedition (1998–2004), F250/F350 Super Duty (1998–2004), Excursion (2000–2005).
• Compatible with E150/E250/E350/E450 vans across noted years (not for natural gas E350 variants).
• Also fits Lincoln Navigator (1998–2000) and VPG MV-1 4.6L (2011–2012).

How do these parts match OEM specifications?

The kit references multiple OEM part numbers so it can act as an affordable replacement while maintaining compatibility. Each coil and plug in the package is produced to match fitment and electrical interface characteristics of the original DG508 family and associated spark plug references.

• Ignition coil cross-reference includes DG508, FD504, FD503 and related OEM codes.
• Spark plug reference given as SP479 / AGSF-22W-MX to match gap and heat range.
• Sold as a full set: 8 coils plus 8 spark plugs for complete bank replacement.

What should I know before installation?

Installation requires basic engine access, correct torque, and proper electrical connections; improper installation can cause engine misfires or damage. If you are not experienced with ignition work, a certified mechanic or professional installer is recommended to ensure safe, reliable fitment and to avoid warranty or vehicle damage risks.

• Follow vehicle service manual torque and sequence for coil mounting.
• Ensure connectors are clean and fully seated to prevent arcing.
• Verify part numbers against your VIN or existing coils—not for 2004+ F-150 5.4L DG511 models.

Will replacing all eight coils and plugs improve drivability?

Replacing worn coils and spark plugs can restore consistent ignition, reduce misfires, and improve throttle response compared to degraded components. While outcomes vary by vehicle condition, replacing the full bank ensures uniform performance across all cylinders.

• Fresh coils restore consistent spark energy across cylinders.
• New spark plugs provide correct gap and firing characteristics.
• Full-set replacement prevents mixing old and new parts that can mask problems.

Who is this kit for? This ultramindz ignition coil and spark plug kit is aimed at owners and mechanics servicing late-1990s to mid-2000s Ford 5.4L trucks, SUVs, and vans (plus specific Lincoln and MV-1 models) that require DG508-type coils. It’s ideal for routine maintenance, restoring engine smoothness, or preparing a vehicle for inspection. Always confirm fitment against your vehicle’s engine code and OEM part references and consider professional installation if unsure.
