Ignition Coil and Iridium Spark Plugs for Ford Mustang (2016-2017) 5.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2016-2017 Ford Mustang GT

What it Does: Restores complete combustion efficiency and eliminates cylinder misfires by replacing degraded coil-on-plug units and worn plugs with matched, high-dielectric ignition components.

The Stock Mustang S550 Ignition Breakdown

The high-compression (11.0:1) Gen 2 Coyote 5.0L engine generates intense cylinder head thermal cycling. Over mileage, factory ignition coil insulation degrades, allowing secondary voltage leakage and micro-arcing. Simultaneously, stock plug electrode erosion increases gap distance, driving up the required firing voltage. Under high cylinder pressures and heavy load, this electrical fatigue manifests as intermittent misfires, erratic idle, spark blowout, and lost low-end torque.

The Engineering Solution

This direct-replacement kit provides eight matched coil packs and eight fine-wire iridium spark plugs. The ignition coils feature premium-grade copper primary and secondary windings encased in high-temperature potting resin to resist heat soak and voltage breakdown. Precision blade terminals and OEM-spec connectors ensure solid continuity. Matched with fine-wire iridium plugs requiring lower firing energy, this package provides a stable, focused spark kernel for rapid flame front propagation, crisper throttle response, and reliable wide-open-throttle ignition.
