Ignition Coil and Iridium Spark Plugs for Jeep Patriot (2007-2017) 2.0L 2.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2007-2017 Jeep Patriot

Restores lost ignition energy and resolves cylinder misfires by replacing worn coil-on-plug packs and eroded plugs with high-dielectric assemblies and fine-wire iridium electrodes.

The Stock Patriot Ignition Breakdown

Under repeated thermal cycling inside the compact MK74 engine bay, the factory ignition coil potting epoxy develops microscopic fractures. This structural breakdown allows secondary ignition voltage to track to ground, causing high-voltage leakage rather than firing across the plug gap. Coupled with OEM electrode erosion that steadily widens the gap, the Chrysler World Engine experiences increased load on PCM drivers, erratic idle speeds, hesitation under acceleration, and persistent P0300-P0304 misfire diagnostic trouble codes.

The Engineering Solution

This comprehensive kit features four direct-replacement ignition coils wound with high-conductivity electrolytic copper and sealed in high-dielectric epoxy to resist thermal degradation and internal shorting. The assemblies incorporate oil- and heat-resistant silicone boots to isolate spark transfer. Matched with four fine-wire iridium spark plugs, the system reduces required ignition ionization voltage, yielding faster flame kernel propagation, complete combustion chamber burn, and consistent spark stability under heavy engine load.
