Ignition Coil and Iridium Spark Plugs for Jeep Compass (2018-2021) 2.4L

Direct-Fit Ignition Coil & Iridium Spark Plug Kit for 2018-2021 Jeep Compass

Complete Ignition Refresh: Restores factory ignition energy, combustion efficiency, and cold-start reliability across all cylinders on the 2.4L MultiAir engine.

The Stock Compass Ignition Breakdown

Under continuous thermal cycling and underhood heat soak, factory coil-on-plug boots and epoxy insulation degrade, leading to dielectric breakdown and secondary voltage leakage. Concurrently, factory spark plug electrodes suffer gap erosion from high-mileage operation, increasing the voltage required to bridge the gap. On the 2.4L Tigershark engine, this leads to cylinder misfires (P0300–P0304), sluggish throttle response, rough idle, and unburnt fuel fouling the catalytic converter.

The Engineering Solution

This comprehensive service kit includes four direct-replacement ignition coils engineered with high-grade internal copper windings and reinforced dielectric housings to resist thermal fatigue and voltage arcing. Matched with four fine-wire iridium spark plugs, the kit delivers high thermal tolerance, low electrical resistance, and a consistent spark kernel under load. Direct-fit blade terminals and factory-matched connectors guarantee seamless installation without wire harness alteration.
