CarBole Ignition Coil Pack DG508 for Ford V8 (Pack of 8) — 4.6L/5.4L Direct-Fit, High-Resistance Construction

CarBole High Performance Coil Pack DG508 is an eight-piece replacement ignition coil set engineered to restore strong, consistent spark for compatible Ford V8 engines (4.6L, 5.4L, and select 6.8L applications).

These curved DG508 coils are built with German-imported insulating wire and Huntsman epoxy to resist corrosion, abrasion, and heat while delivering higher electrical resistance for reliable spark delivery. Designed as a direct-fit replacement for many Ford trucks, vans and SUVs from the late 1990s through the 2010s, the set improves throttle response and reduces misfires when installed correctly. Note: curved coils do not fit 2004-and-newer F150 5.4L models that require a different shape.

How will these coils affect engine performance?

Upgrading worn ignition coils can restore consistent combustion across cylinders, which often yields quicker starts, sharper throttle response, and a smoother idle. While results vary by vehicle condition, replacing faulty coils typically reduces hesitation and misfire codes.

• Stronger spark output for more reliable ignition at each cylinder
• Improved throttle response and smoother low-speed running
• Potential for steadier fuel economy under normal driving

Which vehicles and engines are these coils compatible with?

This 8-piece CarBole DG508 pack is intended for many Ford modular V8 engines—primarily 4.6L, 5.4L and some 6.8L two-valve configurations—found in F-series trucks, Crown Victoria, Mustang, Lincoln, Mercury and several full-size vans and SUVs. Always cross-check your vehicle’s part number and coil shape before purchase.

• Fits many F150/F250/F350 models and Ford vans like E150–E450 (1997–2014 spans)
• Compatible with Crown Victoria, Mustang, Expedition, Navigator, Thunderbird, Mountaineer and more
• Matches numerous OEM numbers (e.g., DG508 and related legacy part codes listed with the product)

What are the build and material highlights of CarBole coils?

CarBole uses high-grade German Elektrisoal wire and Huntsman epoxy to enhance electrical resistance and durability. The materials help resist moisture and abrasion, and the protective potting improves long-term stability in under-hood environments.

• German-imported wire for high electrical resistance and reliable spark
• Huntsman epoxy potting to resist corrosion and vibration damage
• Curved housing design tailored for older modular V8 layouts (verify fit for specific model years)

How easy is installation and what does the package include?

Installation is straightforward for anyone familiar with ignition coil replacement: remove the electrical connector and mounting bolt, swap the coil, and reconnect. The package supplies eight curved DG508 coils, enough to replace all coils on a V8 with one purchase.

• Pack includes 8 curved DG508 ignition coils for full V8 replacement
• Direct-replacement form factor for compatible engines — confirm shape and year fit first
• Works with standard bolt and connector locations used on compatible Ford modular engines

Who is this for: The CarBole DG508 eight-pack is intended for owners and mechanics who need a full set of replacement coils for 4.6L, 5.4L and compatible 6.8L Ford modular engines. It’s a practical option for restoring driveability and clearing cylinder misfires in older trucks, vans and SUVs, provided you verify the curved coil form suits your model year and engine layout.
