Ignition Coil + Spark Plugs for Kia Sorento (2011-2013) 3.5L

Direct-Fit Ignition Coil and Spark Plug Tune-Up Kit for 2011-2013 Kia Sorento (XM)

What it Does: The Ignition Coil + Spark Plugs Kit replaces worn factory ignition components on the 2011-2013 Kia Sorento to eliminate engine misfires, stabilize idle quality, and restore peak combustion efficiency.

The Stock Kia Sorento Coil Degradation Problem

The XM platform equipped with the Lambda II 3.5L V6 packages coil-on-plug assemblies deep within the cylinder head. Over continuous thermal cycling, radiant cylinder heat breaks down the factory coil epoxy encapsulation and embrittles silicone boots. This leads to internal secondary winding shorting, dielectric tracking, and weak spark delivery. Concurrently, factory spark plugs suffer gap erosion and ground electrode wear, driving up ignition circuit resistance and triggering recurring P0300 to P0306 misfire codes under load.

The Engineering Solution

This comprehensive refresh kit pairs high-dielectric insulated coil packs with genuine NGK Iridium spark plugs. Built to interchange with UF546, each coil utilizes premium magnetic copper wire windings to optimize transformation efficiency and maintain consistent high-voltage output across all RPM bands. The included NGK Iridium plugs feature ultra-fine wire center electrodes for lowered required voltage, rapid kernel growth, and superior resistance to spark erosion.

What's Included

• 6x Energy Ignition Coils (Replacement for UF546)
• 6x NGK Iridium Spark Plugs

Frequently Asked Questions & Fitment Warnings

Does this fit the XM Sorento?

Yes, this is a direct fit for the 2011-2013 Kia Sorento equipped with the Lambda II 3.5L engine. Does not fit 2.4L 4-cylinder engines or 3.3L direct-injected models.

Should spark plugs and coils be replaced at the same time?

Yes, replacing plugs and coils together balances secondary circuit resistance across all cylinders to prevent premature degradation of new components.

The Kia Crossover Reliability Standard

Engineered for dependable family utility and heavy towing cycles, this complete ignition refresh restores fuel economy, throttle response, and cold-start reliability without check-engine lights.
