Ignition Coil and Iridium Spark Plugs for Fiat 500 (2018-2019) 1.4L

Direct-Fit Ignition Service Kit for 2018-2019 Fiat 500

What it Does: Restores factory secondary ignition output and stabilizes cylinder combustion across the turbocharged 1.4L MultiAir engine platform.

The Stock 500 Thermal Ignition Breakdown

The compact engine bay of the Type 312 chassis subjects ignition components to intense thermal cycling and heat soak. Over time, OEM coil-on-plug assemblies suffer from dielectric degradation, internal epoxy micro-cracking, and insulation breakdown. Combined with spark plug gap widening under boost pressure, this causes high-RPM misfires, erratic idle quality, and hesitation under load.

The Engineering Solution

This complete 8-piece overhaul kit pairs 4 high-output ignition coils with 4 fine-wire iridium spark plugs. The coil assemblies utilize dense internal copper windings, high-dielectric PBT housing material, and heavy-duty silicone boots to prevent voltage leakage and spark blowout under peak boost. The iridium electrodes offer superior wear resistance against high combustion temperatures, ensuring a lower required firing voltage and consistent flame-front propagation.
