Ignition Coil and Iridium Spark Plugs for Hyundai Santa Fe (2007-2012) 3.3L 3.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2007-2012 Hyundai Santa Fe

What it Does: Complete 6-cylinder ignition tune-up kit engineered to restore factory combustion efficiency, eliminate ignition misfires, and stabilize idle across all operating temperatures.

The Stock Santa Fe Ignition Degradation

The transverse Lambda V6 layout in the CM chassis creates a severe thermal trap, particularly along the rear cylinder bank near the firewall. Over sustained thermal cycles, the factory epoxy casing and secondary coil windings suffer dielectric breakdown and micro-fracturing. Concurrently, standard spark plugs experience accelerated ground electrode erosion from high-dwell ignition cycles, increasing the spark gap beyond factory tolerance. This causes secondary voltage leakage, rough idling, hesitation under load, and P0300–P0306 DTC misfire codes.

The Engineering Solution

This comprehensive service pack pairs high-dielectric coil-on-plug assemblies with ultra-fine-wire iridium spark plugs. Each coil utilizes high-conductivity copper primary and secondary windings encased in reinforced, heat-resistant thermoplastic housing to resist thermal degradation and breakdown. The matched iridium center-electrode spark plugs provide superior spark kernel expansion, require lower firing voltage, and resist carbon fouling to deliver consistent flame propagation under high cylinder pressures.
