Megaflint Ignition Coil 8-Pack for Ford 4.6L/5.4L/6.8L V8/V10 (Yellow) — 15% More Energy, OE Fit

Megaflint 8-pack high-performance ignition coils deliver a stronger spark with about 15% more energy than typical OE coils for compatible Ford V8 and V10 modular engines.

This coil set is built for later-model Ford 2-valve modular engines (4.6L, 5.4L and 6.8L) used across F-150, F-250, F-350, Crown Victoria, Mustang, Expedition, Lincoln and Mercury applications from roughly 1998 to 2008. Manufactured to TS16949-quality standards, these coils are new, tested for durability to OE levels, and backed by a five-year warranty. They match many OEM and aftermarket part numbers, so they fit as a direct-replacement solution when you need consistent ignition performance.

Will these coils fit my Ford engine and which part numbers match?

These ignition coils were designed specifically for 2-valve Ford modular engines in the 4.6L, 5.4L and 6.8L families used in model years around 1998–2008. They cross-reference numerous factory and aftermarket numbers for easier compatibility checks.

• Engine fitment: 4.6L, 5.4L, 6.8L Ford 2-valve modular engines (1998–2008).
• Common compatible part numbers: DG457, DG472, DG491, DG508 and many OEM codes listed.
• Works with vehicles such as F-150, F-250, F-350, Crown Victoria, Mustang, Expedition, Lincoln and Mercury.

How does the "15% more energy" benefit affect drivability?

A higher-energy coil can improve spark consistency across cylinders, which helps maintain stable idle, smoother throttle response and more reliable starts compared with worn or borderline coils. It’s not a performance guarantee, but it reduces misfire risk and helps the ignition system work more effectively under load.

• Stronger spark energy supports consistent combustion and fewer misfires.
• Can improve cold starts and rough-idle conditions tied to weak coils.
• Designed to maintain signal strength under typical driving and towing loads.

Are these coils durable and what warranty/support is included?

Megaflint manufactures these coils to a high-quality standard under TS16949 guidelines, matching OE durability expectations. Each unit is 100% new (not remanufactured) and covered by a five-year warranty, providing long-term reassurance for replacements.

• Construction meets OE-level durability and quality controls.
• New units (not refurbished) for consistent long-term performance.
• Five-year limited warranty from the manufacturer for peace of mind.

What should I check before ordering these ignition coils?

Confirm the calendar year, engine displacement and engine family of your vehicle, and cross-check the listed part numbers. If your vehicle’s service manual or parts lookup shows one of the compatible numbers, these should install without modifications.

• Verify vehicle year/make/model and engine (4.6L, 5.4L, 6.8L 2-valve modular).
• Compare against compatible part numbers like DG457, DG472, DG508 and OEM codes.
• Replace coils with matching electrical connectors and mounting points for direct fit.

Who is this for: Drivers and mechanics who need a direct-replacement ignition coil set for late‑1990s to 2008 Ford modular engines and want improved spark energy and OE‑level durability. This eight-pack is ideal for someone rebuilding or refreshing all coils at once — fleet owners, performance-minded enthusiasts who prioritize consistent ignition, and anyone troubleshooting misfires or ignition-related drivability issues on the listed Ford models.
