B4B BANG 4 BUCK DG511 Ignition Coils Set of 8 for Ford F150 5.4L (2004–2008) — Direct Fit, +15% Energy

B4B BANG 4 BUCK DG511 is a set of eight direct-replacement ignition coils engineered for 5.4L Ford F150 engines (2004–2008), designed to restore ignition performance and deliver up to 15% more energy at the spark plug compared with worn OEM coils.

When an F150’s original ignition coils age they can cause rough idling, misfires, or reduced throttle response. This replacement kit includes eight DG511 coils that match the factory mounting and connector layout for the 5.4L V8 engines used in 2004–2008 models. Each coil is factory tested, built with high electrical resistance materials to create stronger sparks, and coated to resist corrosion and abrasion in underhood environments.

How will these coils affect drivability and engine response?

Replacing failing or weak coils can make the engine run smoother and reduce misfires. The B4B coils are designed to provide consistent high-voltage output to the spark plugs so combustion is more reliable across all cylinders.

• Restores even spark delivery across all eight cylinders
• Reduces hesitation and rough idle caused by weak coils
• Helps recover lost throttle response and engine smoothness

What makes these DG511 coils durable for under-hood conditions?

These coils use materials and coatings that resist moisture, heat, and mechanical wear. Corrosion-resistant finishes and abrasion-resistant housings are intended to withstand the typical stresses found in engine bays.

• High-resistance windings engineered for stable electrical performance
• Protective coatings that limit corrosion and environmental damage
• Robust housing to resist cracking or abrasion over time

Are these coils a direct fit for my 2004–2008 Ford F150 5.4L?

The set is offered as a direct-replacement for many 5.4L Ford F150 applications from 2004 through 2008, matching factory connectors and mounting points. Because ignition coil configurations sometimes vary by build date or engine variant, confirm vehicle fitment before purchase.

• Designed to match factory electrical connectors and bolt locations
• Check the vehicle fitment tool or compare part numbers to OEM coils
• Manufacturer advises verifying year/month of manufacture before ordering

How do these coils compare to OEM parts in terms of energy and testing?

B4B BANG 4 BUCK advertises up to 15% more energy delivered to the spark plug versus worn OEM units, which can translate to a stronger spark under load. Each coil undergoes 100% factory testing prior to shipment to ensure consistent output.

• Tested at the factory for voltage consistency and output reliability
• Engineered to deliver higher energy transfer to spark plugs
• Intended as a cost-effective alternative to replacing individual OEM coils

Who is this for: This eight-piece DG511 ignition coil kit is aimed at Ford F150 owners with the 5.4L V8 (2004–2008) who are experiencing misfires, rough idle, or diminished throttle response and want a full-bank replacement. It suits DIY mechanics and professional technicians who need a tested, corrosion-resistant set that matches factory fitment—but always confirm compatibility with your vehicle’s manufacture date and engine variant before purchase.
