ENA Ignition Coil and Iridium Spark Plug Kit for 3.5L EcoBoost V6 — 6-Pack Direct-Fit Coils & Iridium Plugs (2011–2019)

Complete replacement pack of six ignition coils and six iridium spark plugs engineered for 3.5L EcoBoost V6 engines, compatible with specified Ford and Lincoln models from 2011–2019.

This ENA kit pairs six turbo-specific (3-pin) ignition coil packs with six iridium-tipped spark plugs to restore reliable spark delivery for 3.5L EcoBoost V6 engines. The set is designed as a plug-and-play direct fit for many Ford and Lincoln vehicles—sold as a full bank to simplify maintenance and reduce diagnostic time. Each coil is built with a three-terminal connector and bolt-on mounting to match factory valve-cover locations, while the iridium plugs use a fine center electrode for stable firing and longevity.

Which vehicles will this ENA 3.5L EcoBoost kit fit?

This set is intended for turbocharged EcoBoost 3.5L V6 engines that use the 3-pin coil connector. It supports multiple Ford and Lincoln models across model years primarily from 2011 through 2019; cross-reference your OEM part numbers or use the vehicle fit tool before ordering.

• Ford: F-150 (2011–2016), Explorer (2013–2019), Expedition (2015–2017), Flex (2013–2019), Taurus SHO (2013–2016), Transit 150/250/350 series (2015–2019)
• Police models: Interceptor Utility (2014–2019) and Interceptor Sedan (2013–2017)
• Lincoln: MKT (2013–2019), MKS (2013–2016), Navigator (2015–2017)
• Confirm fitment for turbo (3-pin) connectors only; 2-pin or naturally aspirated engines will not accept these coils.

How do these ignition coils and iridium plugs improve engine performance?

Replacing worn coils and plugs returns consistent voltage delivery and precise spark timing, helping engines run more steadily under load. While results vary by vehicle condition, fresh coils and iridium plugs can reduce misfires, smooth idle, and help maintain combustion efficiency.

• Iridium center tip for longer life and stable spark gap retention.
• Three-terminal coil design matched to factory turbo/EcoBoost connectors.
• Bolt-on mounting and OEM-style dimensions for straightforward installation.
• Sold as a complete six-pack to address all cylinders at once and avoid uneven wear.

What are the technical specifics and part cross-references?

The ENA kit includes six ignition coils and six iridium spark plugs packaged together, with coil specifications that match the factory 12V, valve-cover-mounted, bolt-on units. A detailed list of OEM reference numbers is supplied to help you verify compatibility with your vehicle.

• Coil: 3 terminal quantity, bolt-on mount, valve-cover location, 12V operation.
• Spark plug: iridium center electrode, 0.039" gap, 14 mm thread diameter, 0.63" hex.
• Reference numbers covered: UF646, BL3Z-12029-*, DG549/DG548, GN10638 and others for cross-checking.
• Package contents: 6 coils + 6 iridium spark plugs; includes a 12-month warranty.

How easy is installation and what should I check before buying?

Installation is straightforward for anyone comfortable removing the engine cover and valve cover components: these coils are bolt-on and designed to plug into the factory wiring harness for turbo models. Before purchasing, verify your vehicle uses the 3-pin turbo/EcoBoost coils and confirm fit with the vehicle fit tool or by matching OEM numbers.

• Plug-and-play design—no special tools beyond standard sockets and torque wrench for coil bolts.
• Verify connector type: this kit fits 3-pin turbo coils only; 2-pin or NA engines are incompatible.
• Replace all six at once to ensure consistent spark across cylinders and avoid repeat labor.
• Refer to manufacturer torque specs when tightening coil bolts and spark plugs.

Who this is for: This ENA six-coil and six-plug set is aimed at DIY mechanics, independent shops, and fleet managers who need a reliable, full-bank replacement for 3.5L EcoBoost V6 engines in Ford and Lincoln vehicles. Choose this kit if your vehicle shows misfires, rough idle, or if coils and plugs are due based on service intervals; ensure your vehicle uses the turbo (3-pin) connector before ordering.
