autoexact Ignition Coil Pack and Iridium Spark Plug Kit for 3.5L/3.7L V6 — 6-Cylinder Complete OE-Fit, Pre-Gapped Plugs

Autoexact ignition coil pack and iridium spark plug kit is a complete six-cylinder replacement set designed to restore consistent spark delivery for selected 3.5L and 3.7L Ford, Lincoln, Mazda and Mercury V6 engines.

This kit bundles six epoxy-sealed ignition coils with six fine-wire iridium spark plugs so you can replace all primary ignition components in one service. Manufactured to match OE fitment references (including UF595, UF553, DG520 and similar numbers), the set is intended for naturally aspirated 3.5L/3.7L V6 applications on specific model years. The components are pre-checked and packaged for quicker installation, and the plugs arrive pre-gapped for the recommended torque and performance.

Which vehicles and engines will this kit fit?

The Autoexact kit targets a defined group of V6 models from Ford, Lincoln, Mazda and Mercury. It fits many naturally aspirated 3.5L and 3.7L V6 engines across model years roughly between 2007 and 2015 — but it does not support turbocharged variants.

• Common compatible models: Ford Edge, Taurus, Fusion; Lincoln MKZ, MKX, MKS, MKT; Mazda CX-9, Mazda6; Mercury Sable and Taurus X on listed years.
• Engine sizes confirmed: 3.5L and 3.7L naturally aspirated V6 only.
• Always verify vehicle year, make, model and engine code before ordering.

How does replacing coils and plugs together help my car?

Replacing ignition coils and spark plugs at the same time addresses multiple potential failure points in the ignition chain, reducing the chance of repeat service visits. New coils restore voltage delivery while iridium plugs provide stable, efficient combustion with strong, consistent sparks.

• Reduces misfire, rough idle and hesitation caused by worn ignition parts.
• Simplifies maintenance by supplying six matched coils and plugs in one kit.
• Pre-gapped plugs and durable coil boots help ensure reliable installation and electrical contact.

Are these coils and plugs durable, and what protections do they offer?

The coils use epoxy-potting and heat-resistant housings to withstand temperature, moisture and vibration that cause premature failure. The plugs use iridium electrodes for fine-wire durability and consistent ignition performance over many miles.

• Epoxy-potted coils resist internal arcing and moisture intrusion.
• Iridium spark plugs are pre-gapped for consistent spark and improved longevity.
• Rubber boots and spring contacts help maintain secure electrical connections under load.

What should I know about installation and support?

This kit is designed for direct-replacement installation with basic hand tools and is factory-pre-lubricated with green dielectric grease for smoother seating of coil boots. Recommended plug torque and simple steps are provided to help avoid cross-threading or over-tightening.

• Includes six ignition coils and six pre-gapped iridium plugs for a full cylinder bank service.
• Recommended spark plug torque: approximately 15 N·m (11.06 ft·lb).
• Backed by a 2-year warranty and lifetime technical support; provide VIN or vehicle info if unsure about fitment.

Who is this for: This kit is suited to DIYers, independent shops and fleet technicians who own or service the listed Ford, Lincoln, Mazda and Mercury V6 vehicles and want a single-purchase solution for ignition-related troubleshooting or scheduled tune-ups. If your vehicle matches the specified model years and engine size and you’re experiencing ignition symptoms (misfires, rough idle, reduced throttle response or intermittent check-engine codes related to ignition), this matched coil-and-plug set provides a practical, OE-replacement-style option to restore consistent spark performance.
