Direct-Replacement Ignition Coil and Iridium Spark Plug Service Kit for 2018-2021 Ford EcoSport

What it Does: The ignition coil and iridium spark plug kit replaces deteriorated factory ignition hardware on the 2018-2021 Ford EcoSport to eliminate misfires, restore combustion efficiency, and stabilize idle quality.

The Stock Ford EcoSport Thermal Degradation and Secondary Breakdown

The compact Ford EcoBoost 1.0L Fox inline-three operates under aggressive turbocharger boost profiles and tightly packaged cylinder head architecture. Factory pencil coils on the BK-chassis endure extreme thermal cycling, causing micro-fracturing in the outer epoxy casing. Over time, high cylinder pressures blow out the secondary spark kernel, resulting in high-rpm spark blowout, carbon tracking along the spark plug ceramic, and P0300-P0303 misfire trouble codes under load.

The Engineering Solution

This service kit resolves secondary ignition collapse by combining reinforced coil-on-plug pencil units with high-temp dielectric silicone boots and fine-wire iridium spark plugs. The internal primary and secondary windings feature heavy-gauge copper insulated with premium resin to resist internal arching under continuous peak primary voltage. Paired with fine-wire iridium center electrodes, the kit lowers required firing voltage, accelerates flame-front propagation, and resists the accelerated electrode erosion typical of direct-injected, pressurized combustion chambers.
