Ignition Coil and Iridium Spark Plugs for Jeep Cherokee (2014-2019) 2.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2014-2019 Jeep Cherokee

Direct-fit replacement ignition kit: Restores factory spark energy, stabilizes idle, and eliminates secondary ignition breakdown across all four cylinders on the 2.4L MultiAir engine.

The Stock Cherokee MultiAir Ignition Breakdown

Under sustained thermal cycling and heavy engine bay heat soak, the factory ignition coils on the 2.4L Tigershark platform suffer from internal epoxy degradation and micro-arcing across the secondary windings. Over time, standard factory plugs experience electrode erosion, increasing resistance and demanding higher ionization voltage from fatigued coils. This combination leads to intermittent spark blowout, sluggish throttle response, rough cold starts, and OBD-II misfire fault codes (P0300–P0304).

The Engineering Solution

This complete ignition overhaul kit utilizes heavy-duty copper primary and secondary windings encapsulated in high-grade vacuum-poured dielectric epoxy, encased in heat-stabilized thermoplastic housings to prevent voltage leaks. Paired with fine-wire iridium spark plugs, the assembly lowers ignition voltage demand, ensures rapid flame front propagation, and provides optimal combustion under load without carbon fouling or premature gap widening.
