Ignition Coil + Iridium Spark Plugs for Hyundai Santa Fe (2013-2018) 3.3L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2013-2018 Hyundai Santa Fe

What it Does: The ignition coil and iridium spark plug kit replaces degraded factory ignition components on the 2013-2018 Hyundai Santa Fe 3.3L to eliminate secondary ignition breakdown, stabilize idle, and restore combustion efficiency.

The Stock Hyundai Santa Fe Ignition Breakdown

In the NC chassis platform, the high-compression Lambda II GDI 3.3L V6 places substantial thermal and electrical load on factory ignition modules. Over time, engine bay heat soak degrades internal coil epoxy and breaks down the secondary winding insulation of stock UF546 / 27301-3C000 coils. As spark plug electrodes wear and gaps widen, increased resistance forces higher arc voltages, causing dielectric puncturing, carbon tracking along the silicone boot, and severe high-rpm misfires (DTC P0300–P0306).

The Engineering Solution

This service kit resolves spark delivery failure by matching six heavy-duty ignition coils with fine-wire iridium spark plugs. Each direct-fit coil is built with high-grade electrolytic copper windings potted in high-dielectric epoxy to withstand elevated operating temperatures without internal shorting. The included spark plugs utilize laser-welded iridium center electrodes paired with platinum-tipped ground electrodes, minimizing quench resistance and electrical wear. High-temp silicone boots prevent flashover, ensuring maximum secondary voltage reaches the combustion chamber under full-throttle GDI cylinder pressures.
