Ignition Coil and Iridium Spark Plugs for RAM ProMaster City (2015-2019) 2.4L

Direct-Replacement Ignition Kit for 2015-2019 RAM ProMaster City

What it Does: Restores factory secondary ignition output and complete combustion to eliminate misfires, rough idle, and unburned fuel delivery across all four cylinders.

The Stock ProMaster City Secondary Ignition Breakdown

Commercial stop-and-go duty cycles and tight engine packaging subject the 2.4L Tigershark engine bay to intense thermal soak. Over time, OEM coil insulation degrades, causing dielectric breakdown within the internal epoxy and secondary windings. As factory spark plug electrodes wear and gap width increases, the ignition coils must draw higher saturation current to bridge the gap, leading to thermal stress, spark scatter, intermittent P0300-P0304 cylinder misfire codes, and degraded fuel economy under cargo loads.

The Engineering Solution

This direct-fit overhaul kit provides four high-output ignition coils engineered with high-purity electrolytic copper windings, high-dielectric epoxy potting, and reinforced thermoplastic housings to resist thermal fatigue and internal arc-over. Paired with fine-wire iridium spark plugs, the system reduces the required firing voltage, provides a stable and concentrated flame kernel, improves cold-start reliability, and ensures complete fuel atomization within the MultiAir combustion chamber.
