ENA DG508 Ignition Coils & SP479 Spark Plugs Kit for Ford/Lincoln 5.4L V8 — 8-Pack Direct-Fit, OE Match

This kit pairs eight ENA DG508 ignition coils with matched SP479 spark plugs and is built as a direct-fit replacement for many Ford and Lincoln vehicles from the late 1990s through the 2000s. The components are designed to match OE fitment and firing specifications so you can swap coils and plugs without modifying wiring or engine mounts. Each kit arrives as a full set of eight coils and plugs along with a 24-month warranty for peace of mind.

Will these coils and plugs fit my Ford or Lincoln V8?

Compatibility covers a broad range of Ford applications including F-Series pickups, Excursions, Expeditions and E-series vans, as well as select Lincoln models using the 4.6L, 5.4L and 6.8L V8 engines. Check the listed part numbers and model years against your vehicle's engine code or OEM part reference before ordering to ensure proper match.

• Direct-fit for many 1998–2008 Ford F150/F250/F350 and E150–E450 models
• Compatible with 1998–2005 Excursion and 1998–2004 Expedition 5.4L engines
• Replaces OE references like FD503 and related coil/plug part numbers

How easy is the installation and what tools will I need?

Installation is straightforward for anyone with basic mechanical skills: remove the engine cover (if present), unplug the old coil packs, unseat the spark plug boots, and swap in the new coils and plugs. Torque the spark plugs to factory specifications and ensure electrical connectors are fully seated to avoid misfires.

• Basic hand tools: ratchet, spark plug socket, torque wrench
• No cutting or splicing—plugs and coils are designed for plug-and-play fit
• Follow vehicle torque specs and gap settings where applicable

What performance or reliability improvements can I expect?

Replacing worn coils and spark plugs can help restore consistent spark delivery across cylinders, which supports smoother idle, more reliable starting and steadier throttle response. While not a power upgrade, fresh ignition components reduce the risk of misfires and uneven combustion that degrade drivability.

• More stable idle and crisper throttle response under load
• Reduced chance of cylinder misfires and related engine codes
• Matched coil-and-plug set ensures even firing across all eight cylinders

What’s included and what warranty is provided?

The package contains eight ENA DG508 ignition coils and eight SP479 spark plugs—enough to replace the entire ignition assembly on an eight-cylinder engine. ENA backs the kit with a 24-month warranty covering manufacturing defects for buyer protection.

• Complete set: 8 ignition coils + 8 spark plugs
• Ships ready for installation with OE-style connectors and boots
• 24-month limited warranty against defects

Who is this for: This ENA DG508 + SP479 kit is aimed at DIY mechanics, independent shops, and fleet managers who maintain late-1990s to 2000s Ford and Lincoln full-size trucks, vans and SUVs with 4.6L, 5.4L or 6.8L V8 engines. It's ideal when you need a full ignition refresh—especially if you’re troubleshooting misfires, rough idle, or multiple-cylinder ignition faults and prefer a full-set replacement rather than swapping individual components.
