ultramindz Ignition Coil and Spark Plug Set for Ford/Lincoln 5.4L 2005–2008 — Set of 8, black-boot OE-fit coils

Complete set of eight ultramindz ignition coils and spark plugs engineered to replace OE DG511/UF537 style units on 5.4L Ford and Lincoln V8 vehicles from 2005–2008.

This kit bundles eight ignition coil packs and matching spark plugs designed for Ford 5.4L V8 engines used in F-150, Expedition, F-250/F-350 Super Duty, Lincoln Navigator and Mark LT model years 2005 through 2008. The components match common OE replacement numbers and aim to restore consistent spark delivery and combustion stability when installed correctly. Before ordering, check your vehicle's coil-boot color—this kit fits black-boot configurations, not the brown-boot variants.

Which vehicles and engines are compatible with this ultramindz kit?

These ignition coils and plugs were made for Ford and Lincoln models equipped with the 5.4L V8 built in the 2005–2008 model years. Fitment covers typical gas V8 applications listed by chassis and engine family, but always cross-reference part numbers to be certain.

• Ford F-150 5.4L V8 (2005–2007 before 12/2007)
• Ford Expedition 5.4L V8 (2005–2008)
• Ford F-250 & F-350 Super Duty 5.4L V8 (2005–2008)
• Lincoln Navigator & Mark LT 5.4L V8 (2005–2008)

How do these parts match OE references and what numbers should I check?

The set replaces several factory and aftermarket references so you can confirm compatibility by comparing part codes. Matching OE numbers reduces the risk of ordering the wrong coil or plug for your engine platform.

• Coil cross-references: DG511, UF537, DG-511, FD508
• Manufacturer OE codes: 3L3Z-12029-BA, 3L3U12A366BB, 9W7Z9F593A
• Spark plug references: SP546, 3L3E12405KD, 7C3E12405AB
• Confirm the coil boot color (black boots required for this kit)

What performance and installation considerations should I know?

When replacing ignition coils and plugs as a matched set you can expect uniform spark timing across cylinders when parts are installed properly. Proper torque, connector seating, and using a qualified mechanic for installation helps avoid misfires or coil damage.

• Have a professional mechanic install to prevent damage from over-tightening or incorrect wiring
• Use specified torque for spark plugs and verify coil electrical connectors are secure
• Inspect and replace any damaged boots, wiring, or harness clips during installation
• Check engine codes after installation to confirm no misfire or sensor faults remain

Does this set fit models with different coil boot colors or updated coils?

Compatibility depends on the coil boot style used on your vehicle's original assembly. This set fits black-boot coil assemblies; vehicles that shipped with brown-boot coils are not compatible with these units.

• Verify your original coil boot color before purchasing
• For 2008 models, confirm whether the factory coil had black boots
• If your OEM coils are brown-boot style, source the matching replacement variant

Who is this for: This ultramindz eight-piece ignition coil and spark plug kit is intended for owners, mechanics, and independent shops working on Ford or Lincoln vehicles equipped with the 5.4L V8 from 2005 to 2008 who need a full-bank replacement. It’s ideal when multiple misfires, aging coils, or routine maintenance indicate replacing all eight coils and plugs together. If you are unsure about fitment, provide your VIN and OEM part numbers to a qualified technician before purchase to ensure correct selection and safe installation.
