Ignition Coil & Iridium Spark Plugs for Jeep Cherokee (2014-2022) 3.2L

High-Output Ignition Coil & Iridium Spark Plugs for 2014-2022 Jeep Cherokee (3.2L Pentastar / KL)

What it Does: This complete ignition service kit replaces degraded factory coils and fouled plugs to restore optimal combustion efficiency, eliminate misfires, and stabilize idle in the 3.2L Pentastar V6.

The Stock KL Cherokee Ignition Weakness

Over multiple heat cycles, the factory ignition coils on the 3.2L Pentastar engine suffer from thermal degradation, particularly within the epoxy resin and internal windings. This heat soak leads to increased electrical resistance, weaker spark output, and eventually, erratic misfires under load. Furthermore, factory standard spark plugs often experience accelerated electrode wear, widening the plug gap beyond optimal specifications. This widened gap strains the aging coils further, resulting in sluggish throttle response, poor fuel economy, and potential unburnt fuel entering the exhaust stream, which can prematurely degrade the catalytic converters.

The Engineering Solution

Upgrading to this comprehensive ignition coil and iridium spark plug package resolves inherent secondary ignition failures. The replacement coils feature upgraded internal copper windings and high-dielectric epoxy housing, ensuring consistent voltage output and superior resistance to under-hood thermal cycling. Paired with genuine iridium spark plugs, which boast a microscopic center electrode and exceptional melting point, this kit guarantees a concentrated, precise spark. The iridium construction requires significantly less firing voltage while maintaining the exact factory gap over extended service intervals. This synergy between high-energy coils and efficient iridium plugs maximizes the flame kernel within the combustion chamber, restoring factory horsepower, optimizing fuel atomization, and providing a smooth power delivery.
