CarBole Ignition Coils & Iridium Spark Plugs Set for Ford 6.8L V10 — 10-Coil + 10-Plug Kit, Direct Fit for 1997–2008 F/E Super Dut

CarBole's set pairs ten DG508 ignition coils with ten SP479 iridium spark plugs to replace worn OEM units on 1997–2008 Ford 6.8L V10 engines, restoring reliable spark and consistent engine operation.

This complete 10-coil and 10-plug package is engineered for Ford trucks and vans that use the 6.8L V10 modular engine—covering many F-series Super Duty, E-series Econoline, Excursion and other platform applications from 1997 through 2008. The coils are compact, sealed, and built from high-temperature materials for improved insulation and longevity; the iridium plugs deliver a fine electrode for stable ignition and longer service life than standard copper plugs. The kit is intended as a direct replacement for multiple OE part numbers and fits vehicles that require the DG508-style coil and SP479 plug configuration.

Will this kit fit my Ford F350 or E350 with a 6.8L V10 engine?

Yes—this CarBole bundle is manufactured to match the physical and electrical specifications used in 1997–2008 6.8L V10 modular engines. It replaces many factory part numbers so it covers a broad list of Ford and related models.

• Designed for 6.8L V10 engines in F150/F250/F350/F450 and E150/E250/E350/E450 platforms.
• Also compatible with Crown Victoria, Explorer, Expedition, Mustang, Lincoln and Mercury variants where the DG508 form factor is specified.
• Cross-references multiple OE numbers including DG508, F523, FD-503, 1L2Z12029AA and others.

How do these ignition coils and plugs improve day-to-day drivability?

The coils use professional-grade magnetic cores with precision winding and high-temperature epoxy to reduce leakage and resist thermal deformation, while the iridium spark plugs provide a sharper, more consistent spark. Together they help reduce misfires, smooth idle, and promote steadier throttle response without any engine modifications.

• High-temperature epoxy shell reduces spark leakage and withstands heat cycles.
• Precision-wound core for reliable secondary voltage output.
• Iridium electrode in SP479 increases longevity and consistent firing.

Is installation difficult and what should I expect during the swap?

Installation is straightforward: the DG508 coils are direct plug-in replacements that generally require no additional parts or modifications. Basic hand tools and a torque wrench are typically all that’s needed; replace coils and plugs one cylinder at a time to avoid mix-ups.

• Direct fit coil pack design—no relocation of surrounding components required.
• Replace one coil/plug per cylinder sequentially to maintain firing order.
• Follow torque specs for spark plugs and inspect boot connections for secure fit.

What durability and performance features should I expect from CarBole components?

CarBole builds the coils with insulating epoxy and robust core construction to resist heat and electrical leakage, while the iridium plugs are chosen for wear resistance and longevity. The result is a replacement set aimed at matching or exceeding original equipment service life and maintaining consistent ignition under load.

• Epoxy-encapsulated coil shells for improved thermal and electrical resistance.
• Carbon-buffered core to reduce premature spark generation and wear.
• Iridium plugs for a long-life electrode and stable spark over time.

Who is this for: This 10-coil and 10-plug CarBole kit is suited for owners, fleet managers, and technicians working on Ford vehicles powered by the 6.8L V10 modular engine—especially those restoring ignition performance on Super Duty trucks, Econoline vans, and related models from 1997–2008. It’s ideal when replacing an entire bank or all coils and plugs for consistent performance and simplified maintenance.
