Ignition Coil & Spark Plugs for Ford Explorer / Sport Trac (2006-2010) 4.0L V6

High-Voltage Ignition Coil & Spark Plugs for 2006-2010 Ford Explorer

This direct-replacement ignition coil pack and Motorcraft spark plug kit restores factory spark energy to eliminate misfires and rough idling in the 4.0L V6.

The Stock Explorer Ignition Weakness

Over thousands of heat cycles, the factory epoxy resin within the OEM ignition coil pack degrades, leading to micro-cracking within the housing. Once compromised, moisture intrudes into the primary and secondary windings, causing internal arcing and voltage leaks. This degradation manifests as intermittent cylinder misfires, hesitation under load, poor fuel economy, and eventually triggering persistent P0300 through P0306 diagnostic trouble codes. Furthermore, the factory spark plug electrodes wear down over time, increasing the resistance gap and putting further thermal stress on an already failing coil unit.

The Engineering Solution

This kit resolves these ignition breakdown issues by pairing a high-dielectric epoxy ignition coil pack with genuine OEM Motorcraft spark plugs. The coil block features upgraded internal copper windings engineered to resist thermal breakdown and maintain consistent primary resistance values. The advanced polymer housing is vibration and thermal-shock resistant, completely sealing out moisture and preventing voltage bleed in harsh under-hood environments. Combined with the precise heat range and optimized electrode design of the included Motorcraft plugs, this system ensures a complete fuel burn, restoring lost low-end torque, smoothing out idle fluctuations, and providing reliable cold-start performance even under high-load towing conditions.
