CarBole Ignition Coil Pack for Ford 4.6L/5.4L V8 — DG508 Pack of 8, High-Performance Corrosion-Resistant

CarBole High Performance Coil Pack DG508 is an eight-piece set of ignition coils engineered to restore consistent spark and reliable ignition for Ford 4.6L and 5.4L V8 engines.

This coil pack kit replaces worn or failing ignition coils used on many Ford trucks, vans and SUVs from the late 1990s through the early 2010s. Built with German-imported Elektrisoal wire and Huntsman epoxy, the CarBole DG508 coils are designed to resist corrosion and abrasion while delivering a stable, high-voltage spark. The pack includes eight curved coils matched to original-equipment dimensions for most modular 2-valve V8 engines; note the curved shape makes these incompatible with some 2004-and-later F-150 5.4L variants.

How will these coils affect starting, throttle response and fuel economy?

Replacing degraded coils with the DG508 set can reduce misfires and improve combustion consistency, which typically results in faster starts and more immediate throttle response. Better ignition timing across cylinders means a smoother idle and can help restore lost fuel efficiency without other engine changes.

• Stronger, consistent spark for quicker engine starts
• Reduced misfire and hesitation under load
• Smoother idle and more linear throttle feel
• Potential modest improvement in gas mileage when misfires are corrected

Which vehicles and engines are these coils compatible with?

These coils are manufactured to fit many Ford modular V8 engines used across trucks, vans and passenger cars. They are primarily intended for 4.6L and 5.4L 2-valve engines from roughly 1998–2008, and they list compatibility with numerous Ford, Lincoln and Mercury models across a wide range of part numbers.

• Fits: F150, F250, F350, F450; E-series vans; Crown Victoria; Excursion; Expedition
• Also fits: Mustang, Thunderbird, Lincoln Navigator, Town Car, Mercury models listed
• Engine focus: 4.6L and 5.4L modular V8s (2-valve)
• Not compatible with certain 2004+ F-150 5.4L configurations due to coil curvature

What are the construction and reliability features of the DG508 coils?

CarBole builds these coils with high-grade materials to withstand heat, vibration and exposure common in engine compartments. German-imported insulation wire and Huntsman epoxy increase electrical resistance where needed and protect against corrosion, helping each coil deliver a reliable spark over time.

• German Elektrisoal wire for strong electrical performance
• Huntsman epoxy sealant for moisture and abrasion resistance
• Curved coil housing matched to specific engine layouts
• Sold as an 8-piece pack to replace all cylinder coils at once

How do I identify the correct replacement part numbers?

The DG508 kit cross-references a long list of original part numbers and aftermarket codes so you can confirm fitment before purchase. Check your vehicle’s existing coil part number or consult the included compatibility list to verify the match.

• Cross-referenced part numbers included in product listing
• Compare existing coil label or consult service manual for confirmation
• Contact CarBole support with VIN for precise fit guidance
