Ignition Coil and Iridium Spark Plugs for Dodge Dart (2014-2016) 2.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2014-2016 Dodge Dart

Primary Function: Restores secondary ignition voltage delivery and combustion efficiency across all four cylinders to eliminate misfires, rough idling, and power hesitation under load.

The Stock Dart MultiAir Ignition Breakdown

The 2.4L Tigershark engine operates under high thermal cycles within the compact PF engine bay, leading to premature thermal breakdown of the factory ignition coil potting epoxy and internal copper windings. Over time, high heat degrades the dielectric insulation, causing micro-arcing, secondary voltage leakages, and ignition misfires (DTC P0300-P0304). Paired with standard eroded spark plug gap clearances, this ignition degradation disrupts the electro-hydraulic MultiAir valvetrain's precise combustion sequence, resulting in sluggish throttle response and poor fuel economy.

The Engineering Solution

This direct-replacement ignition service kit features four high-output ignition coils and four fine-wire iridium spark plugs. The coils are engineered with high-conductivity electrolytic copper windings, vacuum-infused dielectric epoxy, and heat-stabilized PBT thermoplastic housings to resist electrical bleed and insulation breakdown under sustained thermal stress. The matching iridium spark plugs feature a laser-welded fine-tip center electrode that reduces ignition voltage demand, minimizes flame kernel quenching, and ensures instantaneous flame propagation across all engine speeds.
