Autowxjq Ignition Coil Connector Pigtail Harness 6pcs for 3.5L EcoBoost — OE-fit, Copper Contacts

Autowxjq Ignition Coil Connector Plug Pigtail Harness is a six-piece replacement wiring set designed to restore reliable electrical connections to the ignition coils on 3.5L EcoBoost turbo engines in select Ford and Lincoln models.

When an ignition coil connector becomes corroded, cracked, or loose it can cause misfires, rough idle, or check-engine lights. This Autowxjq six-pack reproduces OE fit and function for vehicles that use the specific coil pack part numbers listed, offering a direct, bolt-in replacement that uses quality plastics, rubber insulation, and copper conductors for long-term durability. The kit is sold as six pigtail connectors so you can renew a full bank or replace only the faulty units without rewiring the harness.

Which vehicles will these pigtails fit?

These harness connectors are compatible with many Ford and Lincoln models that use the 3.5L EcoBoost turbo engine and the listed coil pack part numbers. They are intended for turbocharged applications only, so verify your engine and part reference before purchasing.

• Ford F-150 (2011–2016) 3.5L EcoBoost
• Ford Expedition, Explorer, Flex, Taurus, Transit, Lobo and Police Interceptor models noted in the features list

How does this replacement match OEM performance?

Autowxjq engineered the housings and contacts to meet or improve on original equipment specifications for fit and electrical integrity. Components are molded and assembled to sit securely on the coil pack while providing corrosion-resistant contact surfaces and insulated wiring for safe power transfer.

• High-quality plastic housing for dimensional stability
• Top-grade rubber insulation around wires for heat and abrasion resistance
• Pure copper conductors to reduce electrical loss and improve conductivity
• Designed for fast, tool-friendly installation that mirrors OE connectors

What are the installation and maintenance considerations?

Installation is straightforward for anyone comfortable accessing ignition coils: unplug the old pigtail, release the retaining clip, and install the new connector. Always work on a cool engine, use basic hand tools, and inspect coil boots and seals while replacing connectors to ensure a complete repair.

• Disconnect the battery before starting work to avoid shorts
• Replace only the damaged pigtails or all six for preventive maintenance
• Check coil boots and spark plugs at the same time for wear
• Ensure clips and retention tabs fully engage for a snug fit

What warranty and part-number compatibility should I know about?

Autowxjq backs these pigtails with a 3-year warranty, giving added confidence after installation. Confirm compatibility by checking the OEM coil part numbers listed with your vehicle’s build or parts manual prior to purchase.

• 3-year limited warranty from Autowxjq
• Compatible with multiple OEM references (UF-646, BL3Z-12029-C, 673-6300, DG549, etc.)
