Ignition Coil and Iridium Spark Plugs for Fiat 500X (2016-2017) 2.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2016-2017 Fiat 500X

What it Does: Replaces degraded factory ignition components with high-dielectric coils and fine-wire iridium spark plugs to eliminate misfires and restore complete combustion in 2.4L engines.

The Stock 500X Ignition Degradation

The compact engine bay of the 2.4L MultiAir creates severe thermal cycling, causing factory coil packs to suffer from dielectric breakdown and micro-cracking in the primary housing. Over time, internal resistance spikes, degrading spark voltage and leading to intermittent secondary-circuit misfires, hesitant cold starts, and unburnt fuel fouling the catalytic converter. Stock standard plugs also experience electrode erosion under high-compression load, widening the gap and straining the ignition system.

The Engineering Solution

This direct-replacement kit features 4 ignition coils wound with high-purity electrolytic copper and vacuum-sealed in high-insulation epoxy to prevent internal arcing and breakdown. Paired with 4 laser-welded fine-tip iridium center-electrode spark plugs, the assembly provides a focused, high-energy spark kernel that resists carbon fouling and delivers rapid flame propagation. Dielectric-resistant thermoplastic boots ensure a moisture-sealed barrier over the valve cover spark plug wells.
