NPAUTO Ignition Coil and Spark Plug Kit for 3.5L V6 EcoBoost – Set of 6, Fits 2011–2017 Ford/Lincoln, OEM-Style Reliability

NPAUTO replacement set includes six ignition coils and spark plugs engineered to restore reliable ignition for 3.5L V6 turbo Ford and Lincoln engines.

If your 3.5L EcoBoost V6 is showing misfires, rough idle, or loss of power, worn coils and plugs are often the root cause. This NPAUTO kit provides six matched ignition coils and spark plugs made to meet or exceed OEM specs and fit a wide range of Ford and Lincoln models from 2011 through 2017 (and select later Transit and Navigator years). The set is sold together so you can replace all ignition points at once and reduce cross-component failure risk.

Which vehicles and engines does this kit fit?

This NPAUTO kit is designed for 3.5L V6 turbocharged engines in many Ford and Lincoln models. It covers F‑150, Expedition, Explorer, Flex, Taurus, Transit variants, and several Lincoln MKS, MKT, and Navigator years listed by fitment.

• Fits 3.5L V6 EcoBoost engines from 2011–2017 across Ford F‑150, Expedition, Explorer, Flex, Taurus, Transit, and Police Interceptor series.
• Compatible with Lincoln MKS/MKT (2013–2016) and Navigator (2015–2017).
• Cross-references include OEM and aftermarket part numbers such as UF646, DG-549, BL3E/BL3Z series and others for easy verification.

How will replacing coils and plugs together help my engine?

Replacing ignition coils and spark plugs at the same time ensures consistent electrical performance across all cylinders. New coils paired with fresh plugs reduce misfires, improve throttle response, and help stabilize idle, especially if one component failed because the other was worn.

• Reduces chance of immediate re-failure from a worn counterpart.
• Improves combustion consistency for smoother running.
• Can restore fuel economy and recover some lost power.

What are the build quality and part references?

NPAUTO manufactures these coils and plugs to match or surpass common OEM tolerances using premium materials. The set lists multiple part numbers and cross-references so installers can confirm correct match for specific vehicle VINs and engine codes.

• Includes six ignition coils and six spark plugs per kit for a full-bank replacement.
• Cross-reference examples: UF646, DG-549, BL3Z‑12029‑A/B/C, BL3E‑12A375‑CA/CB/CC, NP‑6134, SP‑534.
• Produced under QA standards intended to align with factory electrical and thermal requirements.

How should I replace and maintain these components?

Install coils and plugs using proper torque and anti-seize where recommended by your vehicle guide. Replacing the set during routine service intervals or when misfire codes appear helps avoid catalytic converter stress and secondary component damage.

• Follow vehicle service manual torque specs and gap settings for the spark plugs.
• Replace all six items at once for balanced performance and reliability.
• Inspect boots, connectors, and harness for damage during installation.
