Ignition Coil and Iridium Spark Plugs for Ford C-Max (2013-2018) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2013-2018 Ford C-Max

Restores Peak Combustion Efficiency: Replaces degraded factory coils and worn plugs to eliminate intermittent misfires, restore hybrid fuel economy, and ensure seamless ICE transitions.

The Stock C-Max Ignition Breakdown

The 2.0L Atkinson-cycle powertrain in the C-Max experiences frequent start-stop thermal cycling inherent to hybrid operation. Over extended mileage, under-hood heat soak breaks down the OEM secondary winding insulation and cracks aging coil boots. This dielectric breakdown allows high-voltage arc leakage, leading to intermittent hesitation, rough idle, increased emissions, and persistent P0300-P0304 misfire diagnostic trouble codes.

The Engineering Solution

This comprehensive service kit features four coil-on-plug units wound with high-grade internal copper wiring and sealed in premium dielectric epoxy to withstand intense thermal stress. Direct-fit blade connectors ensure optimal electrical conductivity without harness modification. Paired with four fine-wire iridium spark plugs featuring laser-welded tips, the kit delivers a concentrated spark kernel at lower firing voltages for rapid, complete combustion.
