Ignition Coil and Iridium Spark Plugs for Jeep Cherokee (2019-2020) 2.0L

High-Output Ignition Coil and Iridium Spark Plug Kit for 2019-2020 Jeep Cherokee

What it Does: The Ignition Coil and Iridium Spark Plug Kit restores secondary ignition energy and flame-front stability on the 2019-2020 Cherokee to eliminate high-boost misfires and rough idling.

The Stock Jeep Cherokee High-Thermal Degradation

The forced-induction 2.0L platform generates high cylinder pressures and severe heat cycling within the deep spark plug wells. Over time, OEM pencil coils on the KL platform suffer dielectric breakdown in the secondary windings and epoxy degradation from heat soak. Paired with standard plug gap erosion under peak boost pressures, this results in spark blowout, sluggish throttle tip-in, decreased fuel efficiency, and P0300-series cylinder misfire diagnostic trouble codes (DTCs).

The Engineering Solution

This comprehensive tune-up kit replaces tired factory hardware with reinforced coil-on-plug units and high-durability fine-wire iridium spark plugs. The pencil coils feature high-temperature thermoplastic housings, high-dielectric epoxy potting, and optimized copper windings engineered to resist insulation breakdown under sustained thermal load. The matching iridium plugs offer exceptional resistance to electrical erosion and elevated melting points, ensuring a consistent, concentrated spark kernel that prevents quenching in high-boost forced-induction environments.

Frequently Asked Questions

Does this fit the KL Cherokee?
Yes, this is a direct fit for the 2019-2020 Jeep Cherokee equipped with the GME T4 2.0L turbocharged engine.

Are the spark plugs pre-gapped for forced-induction operation?
While pre-gapped to factory specifications, always verify the electrode gap with a feeler gauge prior to installation to ensure precise boost containment.

The Jeep Trail Durability Standard

Engineered to handle sustained off-camber crawl heat and heavy highway load, this direct-fit ignition kit delivers reliable cold starts, consistent combustion under high load, and peace of mind on and off the trail.
