B4B BANG 4 BUCK Ignition Coil Pack Set of 8 for Ford V8 4.6/5.4L — Curved‑Boot, 26kV Rated

B4B BANG 4 BUCK ignition coil pack set of 8 (DG508-style) is a direct-replacement coil kit engineered to restore reliable spark and reduce misfires for compatible Ford V8 engines.

These eight black coil packs are built to match OE fitment for many Ford, Lincoln and Mercury vehicles using curved-boot coils. Molded from GE Valox high-voltage resin and rated up to 26,000 V, this set replaces worn or damaged coils on a range of 4.6L and 5.4L V8 engines (confirm compatibility using the year/make/model selector and part references before purchase). Note: they do not fit 2004 and newer F-150 5.4L engines that require DG511 coils.

How do these coils improve engine performance on vehicles with misfires?

Replacing degraded coils with this set helps restore consistent ignition timing and combustion across all cylinders, which reduces misfire codes and rough idle. The improved dielectric resin and primary resistance spec aim to deliver stable, repeatable spark under load.

• Set of 8 coils for full-bank replacement
• Primary resistance: 0.660 ohms for predictable current flow
• GE Valox high voltage resin resists breakdown up to 26,000 V
• Tested to perform reliably for over 15,000 miles in validation runs

Which vehicles and part numbers is this pack compatible with?

This coil pack fits many Ford, Lincoln and Mercury models equipped with curved-boot coil style on 4.6L and 5.4L V8 engines from the specified years. Compatibility should be cross-checked with the listed reference numbers and your vehicle details prior to ordering.

• Common references: DG508, DG457, 1972290, 1L2U12029AA and others
• Fits models including F-150 (certain years), Expedition, Crown Victoria, E-Series vans and Excursion
• Does not fit 2004+ F-150 5.4L V8 that require DG511 coils
• Check whether your boots are curved or straight; these are curved-boot coils

What are the construction and electrical specifications?

Each coil is produced using professional-grade, high-voltage di-electric resistant plastic (GE Valox), designed to withstand ignition demands. The coils’ electrical and physical specifications mirror OE-style parameters to ensure fit and function when installed as a direct replacement.

• Maximum voltage rating: 26,000 V
• Coil style: coil pack with curved boot
• Primary resistance: 0.660 ohms for consistent spark delivery
• Durability testing: validated to perform well beyond initial break-in miles

How should I confirm I’m ordering the correct coil set?

Before purchase, use the vehicle year/make/model selector and review the interchangeable part numbers provided. Visually inspect your vehicle’s current coil boots (curved vs. straight) and compare reference part numbers to avoid fitment issues.

• Use the product’s compatibility dropdown to match year/make/model
• Cross-check listed reference numbers against your OEM part number
• Confirm boot shape: these are curved-boot coils for the specified applications
• Do not select for 2004+ F-150 5.4L that require DG511 coils

Who is this for: Mechanics, DIY enthusiasts and fleet operators who need a cost-effective, full-bank ignition coil replacement for compatible Ford, Lincoln and Mercury V8 vehicles. This set suits users seeking OE-style electrical specs, curved-boot fitment and a proven replacement option to address misfires and ignition reliability—provided they verify compatibility with their vehicle and listed part references.
