A-Premium Ignition Coil Pack and Iridium Spark Plug Kit — Set of 4 for Ford 2.0–2.5L, OEM-fit

A-Premium's set of four ignition coil packs paired with four iridium spark plugs replaces worn ignition components to restore consistent spark, smoother idling and reliable starts for compatible Ford, Lincoln and Mercury 4‑cylinder engines.

This matched kit bundles four bolt‑on ignition coils and four iridium‑tipped spark plugs engineered to the original equipment form, fit and electrical specifications listed by A‑Premium. The components are designed for direct replacement on a range of naturally aspirated and hybrid 2.0L–2.5L engines used across Ford C‑Max, Escape, Fusion, Transit Connect and equivalent Lincoln and Mercury models, offering OEM‑style mounting, blade terminals and specified primary/secondary resistance values.

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

Replacing aging coils and plugs helps reestablish strong, consistent spark energy at each cylinder, which supports steadier idling, more reliable cold starts and smoother throttle response. The iridium central electrode is harder and finer than conventional metals, extending plug life and maintaining gap integrity for longer service intervals.

• Iridium + platinum electrode for extended longevity and stable spark
• Specified primary resistance 0.50–0.62 Ω and secondary 5.6–6.8 kΩ for proper ignition characteristics
• Bolt‑on mounting with blade terminals for straightforward, secure installation
• Factory‑style thread diameter 14 mm and recommended installation torque 15 N·m

What should I expect when installing this replacement kit?

Installation typically involves removing the old coil pack assembly from the valve cover, disconnecting electrical connectors, unbolting the coil mounts and swapping in the new coils and plugs. Basic hand tools and a torque wrench are recommended to seat the plugs to the specified 15 N·m and ensure reliable connections.

• Coil terminal quantity: 2 with blade‑type connectors for OEM compatibility
• Mount type: bolt‑on to valve cover—no adapter required
• Gap pre‑set: 1.2–1.3 inches (factory spec) to maintain proper spark distance
• Secondary checks: clear engine codes after install and test idle/spark performance
