Ignition Coil and Iridium Spark Plugs for Kia Sportage (2011-2016) 2.0L

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

What it Does: The ignition coil and iridium spark plug kit restores factory spark energy and stabilizes combustion across the cylinder bank on the 2011-2016 Kia Sportage to eliminate misfires, hesitation, and unburnt fuel cycles under high boost.

The Stock Kia Sportage Ignition Breakdown

The factory ignition coils and plugs on the SL chassis Kia Sportage equipped with the direct-injected Theta II (G4KH) 2.0L Turbo endure extreme thermal cycling and high cylinder combustion pressures. Over time, heat soak causes the internal copper windings and potting epoxy within the factory pencil coils to degrade, resulting in secondary breakdown and micro-arcing. Simultaneously, direct-injection carbon fouling and gap erosion increase resistance on aged plugs, prompting spark blowout, rough cold idles, reduced fuel economy, and flashing P0300-P0304 misfire diagnostic trouble codes.

The Engineering Solution

This comprehensive tune-up kit restores reliable ignition under load by combining heavy-duty replacement pencil coils with fine-wire iridium spark plugs. The replacement coils use premium insulated copper primary and secondary windings encapsulated in high-grade dielectric epoxy to eliminate arc-over and handle high-heat engine bay conditions. Paired with high-melting-point iridium core spark plugs, this setup lowers ignition voltage requirements, prevents quenching, and delivers sharp, consistent flame front propagation to safeguard turbocharger spooling and direct-injection efficiency.

Frequently Asked Questions

Does this fit the SL Sportage?
Yes, this is a direct fit for the 2011-2016 Kia Sportage equipped with the 2.0L Theta II turbo engine.

Do these iridium spark plugs require gapping prior to installation?
No, these iridium plugs come factory pre-gapped for direct installation; manually gapping fine-wire iridium tips risks fracturing the center electrode.
