Ignition Coil and Iridium Spark Plugs for Hyundai Santa Fe (2010-2012) 2.4L

Direct-Fit Ignition Tune-Up Kit for 2010-2012 Hyundai Santa Fe

What it Does: Restores factory secondary ignition performance and peak combustion efficiency on the Theta II 2.4L inline-4 engine.

The Stock Santa Fe Ignition Degradation

Under sustained thermal cycling within the CM chassis engine bay, factory coil boots and internal primary/secondary windings undergo dielectric breakdown. Over time, high heat degrades the internal epoxy insulation, inducing micro-arcing and secondary voltage leakage. Paired with standard plug erosion that widens the spark gap, this degradation causes cylinder misfires (P0300-P0304 codes), erratic idle, unburned fuel wash, and loss of throttle response under load.

The Engineering Solution

This comprehensive service kit pairs four direct-fit coil-on-plug assemblies with fine-wire iridium spark plugs. Built with high-conductivity copper primary and secondary windings, each coil delivers a consistent high-voltage output across all RPM bands. The iridium electrode core provides low voltage demand and high thermal resistance against spark erosion. Fitted with heat-resistant silicone boots, direct-fit blade terminals, and OE-spec connectors, this package eliminates current tracking and guarantees immediate cold-start ignition.
