Ignition Coil + Iridium Spark Plugs for Hyundai Santa Fe (2019-2020) 2.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2019-2020 Hyundai Santa Fe (TM)

What it Does: The Ignition Coil and Iridium Spark Plug Kit replaces degraded factory ignition components on the 2019-2020 Santa Fe to restore optimal secondary voltage, eliminate misfires, and stabilize combustion efficiency under load.

The Stock Hyundai Santa Fe Ignition Breakdown

The direct-injected Theta II G4KJ engine operates under high cylinder pressures and intense thermal cycling. Over time, the factory coil-on-plug boots suffer from dielectric breakdown, thermal degradation, and micro-cracking in the epoxy casing. This leads to internal core insulation failure, voltage leaks to the cylinder head, and premature carbon fouling on OEM plugs. Left unaddressed, elevated internal primary winding resistance stresses the PCM drivers, causing rough idle, hesitation under acceleration, and persistent P0300-P0304 diagnostic trouble codes.

The Engineering Solution

This matched overhaul kit pairs high-dielectric coil-on-plug units with genuine NGK Iridium IX (93175) spark plugs. The replacement coils feature reinforced copper primary and secondary windings potted in high-grade heat-resistant epoxy to resist breakdown caused by underhood thermal saturation. Coupled with ultra-fine wire iridium center electrodes, this package requires significantly less secondary firing voltage to bridge the gap, preventing high-RPM spark blowout and providing stable combustion throughout the powerband.

Frequently Asked Questions

Does this fit the TM Santa Fe?

Yes, this is a direct fit for the 2019-2020 Hyundai Santa Fe equipped with the 2.4L Theta II G4KJ engine.

Should spark plugs and coil packs be replaced at the same time?

Yes, pairing new ignition coils with fresh iridium plugs ensures consistent primary-to-secondary resistance and prevents old, high-resistance plugs from prematurely killing new coil windings.

The Hyundai Reliability Standard

Engineered to meet precise OE resistance specifications, this direct-fit ignition tune-up assembly restores clean burning cycles, reliable cold-start crank performance, and long-term drivetrain dependability for your daily cross-town commute or family highway travel.
