Ignition Coil and Iridium Spark Plugs for Ford Edge (2020-2023) 2.7L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2020-2023 Ford Edge

What it Does: The Ignition Coil and Iridium Spark Plug Kit replaces degraded factory ignition components on the 2020-2023 Ford Edge to eliminate under-boost misfires and restore complete combustion efficiency.

The Stock Ford Edge Ignition Breakdown

The twin-turbocharged 2.7L EcoBoost Nano V6 generates high cylinder pressures within the compact CD4 engine bay. Over prolonged duty cycles, factory pencil coils face heavy thermal radiation from adjacent cylinder heads and turbo plumbing. This sustained heat soak breaks down the internal dielectric epoxy potting and degrades the secondary winding insulation. Simultaneously, standard plug electrode gaps widen from high-boost spark erosion. Together, these factors cause high-voltage leakage, erratic dwell times, high-RPM spark blowout, and driveability hesitation triggered by cylinder misfire fault codes.

The Engineering Solution

Designed specifically to handle forced-induction combustion demands, this direct replacement kit restores secondary ignition reserve. Each coil-on-plug pencil unit utilizes heavy-duty magnetic core laminations and high-temperature copper windings insulated with premium thermoset epoxy to prevent arcing and internal shorting. Paired with fine-wire iridium spark plugs featuring thermal-conductive copper core ground straps, this setup reduces required firing voltages, stabilizes flame kernel expansion, and ensures misfire-free operation under heavy load. The set directly supersedes OEM part numbers KT4Z12029A and UF-827.
