CarBole Ignition Coil & Spark Plug Kit — 10‑Pc Set for 6.8L V10 Ford, Direct-Fit with Iridium Plugs

CarBole's set includes ten DG508 ignition coils and ten SP479 iridium spark plugs engineered to replace factory coils and plugs on 6.8L V10 Ford engines from 1997–2008.

This complete 10-pack replaces worn ignition coils and spark plugs on many Ford E- and F-series vehicles, providing a direct-fit, plug-and-play replacement that mirrors OEM mounting and firing positions. The coils use a durable high-temperature epoxy shell and precision winding for stable ignition, while the iridium plugs offer consistent spark performance. The kit is sold as a matched set to simplify maintenance for fleet, commercial, and heavy-duty vehicle owners.

Will these coils and plugs fit my Ford V10 engine?

These parts are designed specifically for 6.8L V10 modular engines built into many Ford trucks and vans from 1997 through 2008. Fitment targets include E150/E250/E350/E450, F150/F250/F350/F450 series, Econoline, Excursion, Expedition, and several Lincoln/Mercury derivatives.

• Compatible part numbers include DG508, F523, E213, E262, E409 and common OEM references.
• Engine-specific application: 6.8L V10 modular (1997–2008).
• Direct plug-in design for original coil mounting locations—no modifications required.

How do these parts improve ignition reliability?

The DG508 coils are wound with professional-grade magnetic steel and insulated with high-temperature epoxy to resist heat and prevent spark leakage. Paired with iridium spark plugs, the combination helps maintain consistent combustion and easier starting under load.

• Precision winding reduces energy loss for stronger secondary spark.
• Epoxy shell resists thermal deformation and isolates high-voltage leaks.
• Iridium electrodes promote stable sparking and longer service intervals.

What should I expect during installation and maintenance?

Installation is straightforward: each coil is a direct replacement that plugs into the original harness and mounts in OEM positions. No special tools or relocation of surrounding components are required; standard hand tools suffice for coil and plug replacement.

• Direct plug-and-play coils—no adapter or rewiring needed.
• Use recommended torque values for spark plugs and snug mounting bolts for coils.
• Replace all ten coils and plugs as a set for even performance across cylinders.

Are these new aftermarket parts or remanufactured units?

The kit is engineered as new aftermarket replacement components built to meet typical OEM dimensions and electrical characteristics. Quality control emphasizes fit, insulation integrity, and winding precision to match factory expectations.

• New coils with silicon magnetic cores and epoxy encapsulation.
• Iridium spark plugs designed for longevity and consistent spark gap retention.
• Sold as a matched 10-coil + 10-plug kit to simplify service procedures.

Who is this for: This CarBole ignition coil and spark plug set is ideal for fleet managers, commercial vehicle owners, and DIY mechanics maintaining 6.8L V10 Ford vans, trucks, and SUVs between 1997 and 2008. It suits anyone replacing multiple coils and plugs at once who wants a direct-fit, reliable aftermarket option that restores consistent ignition across all cylinders.
