CarBole ignition coils and spark plugs kit — Set of 10 for Ford 6.8L V10, direct-fit iridium

This complete set of 10 ignition coils and 10 iridium spark plugs is built to match OEM fitment for many Ford trucks and vans equipped with the 6.8L V10 modular engine produced from 1997–2008. Each coil is engineered with a high-temperature epoxy shell and precision winding that resists heat and electrical leakage, while the iridium spark plugs offer a durable electrode for consistent combustion. The package is designed for direct replacement—no modification required—so you can swap out old, failing parts quickly and get back on the road.

How will these ignition coils and spark plugs improve engine performance?

Fresh coils and iridium plugs help restore consistent spark timing and strength, which reduces misfires, smooths idle, and aids throttle response. While not a tuning device, replacing degraded ignition components often returns drivability to expected levels.

• Stronger, more consistent spark delivery from each cylinder
• Reduced engine misfires and smoother idling
• Iridium plugs provide longer electrode life versus standard plugs
• Direct-fit design helps preserve factory ignition timing and performance

Are these parts compatible with my Ford vehicle?

The set targets Ford vehicles that use the 6.8L V10 modular engine across many F-series trucks and full-size vans. Compatibility covers a broad list of OEM part numbers and common cross-references, but always verify with your VIN or engine code before purchase.

• Engineered for 6.8L V10 engines found in 1997–2008 models
• Common fits include F150/F250/F350/F450 and E150–E450 Econoline models
• Also listed for many Lincoln, Mercury, and Ford full-size applications
• Check cross-reference part numbers like FD-503, F523, and similar listed codes

What makes the DG508 coil and SP479 spark plug durable and serviceable?

Durability comes from careful material choices and manufacturing processes: a magnetic steel core and precision winding for the coil, plus a hardened shell that resists heat and electrical breakdown. The iridium plugs use a fine, wear-resistant electrode that preserves gap integrity longer than conventional plugs.

• High-temperature epoxy shell prevents spark leakage and deformation
• Magnetic steel core and precision winding for stable electrical output
• Carbon-strip insulation buffers reduce unintended arcing
• Iridium electrode extends service intervals compared to standard plugs

How easy is installation for a DIY mechanic?

Each coil is a direct plug-in replacement that requires no modification to surrounding components in most applications, and spark plugs follow the same basic installation steps as OEM parts. Basic hand tools and a torque wrench are recommended for correct spark plug seating.

• Direct-fit coils match factory mounting points and connectors
• Spark plugs install like stock units—use correct torque and gap specs
• Typical replacement time: moderate for full 10-cylinder service
• Works well for professional shops and experienced DIYers

Who this kit is for: Owners and technicians working on Ford vehicles with the 6.8L V10 modular engine who need a full-bank ignition refresh. This set suits fleet maintenance, restoration projects, and anyone experiencing misfires, rough idle, or aged ignition parts. Always confirm compatibility with your vehicle's model year, engine code, and OEM part references to ensure proper fitment before installation.
