Ignition Coil and Iridium Spark Plugs for Kia Sportage (2011-2016) 2.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2011-2016 Kia Sportage

What it Does: Restores factory secondary ignition performance, eliminating misfires and rough idle caused by degraded ignition coils and fouled plugs in the 2.4L Theta II engine.

The Stock Sportage Ignition Breakdown Under Thermal Cycling

The Theta II engine bay subjects factory coil-on-plug modules to extreme thermal cycles and secondary voltage breakdown over time. High engine temperatures cause internal epoxy insulation and primary/secondary copper windings to degrade, leading to high-voltage leakage, erratic spark energy, cylinder misfires (P0300–P0304), and unburned fuel entering the catalytic converter. Worn factory plugs increase the required firing voltage, accelerating coil stress and causing hesitation under load.

The Engineering Solution

This comprehensive tune-up kit features four direct-replacement ignition coils engineered with high-grade copper windings and premium dielectric resin encapsulation to resist thermal degradation and prevent dielectric breakdown. Paired with fine-wire iridium spark plugs, the assembly provides a focused, high-intensity spark with lower required voltage, ensuring complete air-fuel combustion, stable cold starts, and consistent throttle response across all operating conditions.
