CarBole Ignition Coil Pack for Ford 4.6L/5.4L V8 — Pack of 8 DG508, Curved Coil, High-Durability

CarBole DG508 high-performance ignition coil pack set (8 pieces) replaces worn coils on many Ford 4.6L and 5.4L V8 engines to restore consistent spark, reduce misfire, and improve throttle response.

These eight curved DG508 ignition coils from CarBole are engineered as direct-fit replacements for many Ford modular engines—commonly found on F150, F250, F350, E-series, Expedition, Mustang, Crown Victoria, Lincoln and other models from the late 1990s through early 2010s. Built with Germany-imported Elektrisoal wire and Huntsman epoxy, the coils prioritize electrical resistance control, corrosion resistance, and thermal durability. They are supplied as a full set of eight to cover V8 ignition systems that use individual coil-on-plug units.

Will these coils fit my truck or SUV?

Compatibility covers a wide range of Ford vehicles that use 4.6L and 5.4L modular V8 engines from approximately 1997–2014, excluding certain 2004-and-newer curved-coil F150 applications. Always cross-check your OEM part numbers or the vehicle’s original coil number before purchase.

• Designed for many Ford F-series (F150, F250, F350, F450) and E-series vans.
• Commonly fits Crown Victoria, Mustang, Lincoln, Expedition, Explorer, Thunderbird and Mercury models listed in the spec sheet.
• Compatible part numbers include DG508 and a long list of equivalent OEM references—compare with your vehicle's part number.
• Note: curved coil design does not fit some 2004+ F150 5.4L variants.

How do these coils influence engine performance and drivability?

By delivering a more consistent and stronger spark, these coils can help reduce misfires and hesitation, improving ignition stability across cylinders. That tends to smooth idle, sharpen throttle response, and can contribute to more reliable starts and steadier acceleration—results depend on the overall condition of the ignition and fuel systems.

• Higher electrical resistance control for steady spark delivery.
• Curved coil design tailored to specific engine layouts for a secure fit.
• Better corrosion and abrasion resistance for longer service life.
• Sold as a full set of 8 to replace all V8 coils simultaneously.

What materials and build quality should I expect?

CarBole constructs these coils using Germany-imported Elektrisoal wire and Huntsman epoxy resin to improve insulation and structural integrity under high voltage and heat. The materials are selected to resist chemical corrosion and physical wear that commonly affect ignition components over time.

• Elektrisoal wire for improved electrical performance and insulation.
• Huntsman epoxy for thermal stability and moisture protection.
• Durable housings and terminals to resist abrasion and environmental exposure.
• Produced to match form, fit and function of many OEM coil packs.

How should I replace and maintain these coils?

Replacement is straightforward when following factory service procedures: disconnect battery, remove engine cover if required, unplug the coil electrical connector, unbolt and remove old coil, and install the new coil with proper torque. Regular inspection of boots, connectors and spark plugs helps preserve ignition health.

• Replace all eight coils at once when one fails to ensure uniform performance.
• Inspect spark plugs and wiring harness for wear during coil swap.
• Use correct torque values and dielectric grease on boots when recommended.
• Keep electrical connectors clean and dry to prevent misfires.

Who this product is for: CarBole DG508 coil packs are intended for owners and technicians working on Ford vehicles with 4.6L, 5.4L and compatible modular V8 engines who need a cost-effective, full-set ignition coil replacement. They suit fleet and private owners who prefer replacing all coils at once for consistent spark performance, and DIYers who are comfortable following basic ignition system service steps. Verify vehicle fitment and OEM part numbers before ordering to ensure compatibility with your specific year and engine variant.
