Which vehicles will this ENA coil pack fit?

This coil pack fits many naturally aspirated V6 applications from Ford, Lincoln, Mazda and Mercury. Compatible models include F-150, Explorer, Edge, Mustang, Taurus, Flex, Transit series, Lincoln MKX/MKZ/MKS/MKT and Mazda CX-9 and 6 across the listed years.

• Ford F-150 (2011–2017) 3.5L and 3.7L, Mustang (2011–2016) 3.7L

How does this coil pack match the original part?

ENA lists cross-reference numbers such as UF553, DG520 and factory codes including 7T4Z12029DA and related variants, making it suitable as a replacement for those originals. The coil uses the same bolt-on mounting to the valve cover and a two-terminal electrical connection consistent with OEM expectations.

• Direct-fit mount type: bolt-on to valve cover for straightforward replacement
• Terminal quantity and wiring match original two-terminal designs
• Electrical specification: standard 12V ignition coil operation
• Reference numbers provided to help verify compatibility with OEM parts

What should I expect during installation and performance?

Installation is intended to be plug-and-play for mechanics or knowledgeable DIYers: remove the old coil, transfer any brackets if needed, and bolt the ENA unit in place. Performance expectations are to restore consistent spark output and reliable firing for cylinders served by this coil, provided the rest of the ignition system and fuel/tracking components are in good condition.

• Simple swap: unplug electrical connector, unbolt old coil, install ENA coil
• Works with stock spark plug gaps and standard 3.5L/3.7L engine settings
• Pack ships as a single coil—replace only failed positions or consider sets for multiple failures
• 12-month warranty covers manufacturing defects—keep purchase proof

How do I confirm this part is right for my vehicle?

Always verify by checking the listed cross-reference numbers against your existing coil or your dealer parts information. Use the vehicle fitment list (years and engine sizes) and enter your vehicle details in your parts account or Amazon Garage to reduce the risk of ordering an incompatible coil.

• Compare part references: UF553, DG520 and factory codes provided by ENA
• Confirm engine size (3.5L or 3.7L) and naturally aspirated configuration
• Check the model years listed for each vehicle in the fitment details
• Contact the seller or check the vehicle’s service manual if unsure

Who is this for: This ENA ignition coil pack is aimed at owners and technicians working on naturally aspirated 3.5L and 3.7L V6 engines in Ford, Lincoln and Mazda vehicles who need an OEM-referenced replacement. It’s useful for repairing misfire-related issues on a specific cylinder, restoring ignition reliability after a coil failure, or stocking commonly demanded replacement parts in an independent repair shop. Always double-check fitment against your vehicle’s year, engine code and the original coil part number before purchasing.
