autoexact Ignition Coil and Iridium Spark Plug Kit — 6-Pack for 3.5L/3.7L V6 (Pre-Gapped, Sealed Coils)

The Autoexact ignition coil pack and iridium spark plug kit is a complete, direct-replacement set of six coils and six pre-gapped iridium plugs engineered to restore ignition performance on compatible 3.5L and 3.7L V6 Ford, Lincoln, Mazda, and Mercury vehicles.

This kit bundles OE-style ignition coils (UF595/UF553/DG520 equivalents) with fine-wire iridium spark plugs to provide a one-stop replacement for worn ignition components in selected naturally aspirated 3.5L and 3.7L engines. It’s designed for owners who want to eliminate ignition-related drivability issues and avoid sourcing parts separately. The coils are epoxy-potted and sealed for heat and moisture resistance, while the iridium plugs come pre-gapped and factory-lubricated for straightforward installation.

Which vehicles and engines will this kit fit?

This kit is intended for specific naturally aspirated V6 applications. Confirm year, make, model and engine before purchasing to ensure fitment. It does not support turbocharged engines.

How can replacing the coils and spark plugs help my car’s performance?

Worn coils or spark plugs can cause misfires, rough idle, hesitation, or a check engine light. Swapping both components at once reduces the chance of repeated labor and mismatched wear, helping restore smoother combustion when ignition parts are the root cause.

• May reduce misfire-related codes such as P0300–P0308 when ignition parts are faulty
• Iridium plugs offer stable arc and long service life compared with standard plugs
• Sealed, epoxy-potted coils resist internal arcing and moisture intrusion

What’s included and what should I expect during installation?

The kit contains six ignition coils and six pre-gapped iridium spark plugs plus factory-applied dielectric grease for the boots. It’s made for direct replacement with common hand tools; recommended spark plug torque is 15 N·m (11.06 ft·lb).

• Complete set: 6 coils + 6 iridium spark plugs — no separate sourcing needed
• Pre-gapped plugs and pre-lubricated boots for easier, cleaner installs
• Basic tools required; coil connectors and springs included for secure fit

What build quality and support does Autoexact provide?

Each coil is quality-checked for electrical performance and fit prior to packaging. The coils use heat-resistant housings and sealed construction; plugs are fine-wire iridium for consistent spark. Autoexact provides a 2-year warranty and lifetime technical support for buyer assistance.

• Epoxy-potted coils to reduce moisture and vibration-related failures
