Ignition Coil and Iridium Spark Plugs for Hyundai Palisade (2020-2024) 3.8L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2020-2024 Hyundai Palisade

What it Does: The Ignition Coil and Iridium Spark Plug Kit restores complete combustion efficiency, stabilizes idle, and eliminates ignition misfires on the 2020-2024 Hyundai Palisade 3.8L V6.

The Stock Hyundai Palisade Secondary Voltage Degradation

Factory pencil coils on the direct-injected Lambda II G6DN 3.8L engine are subject to extreme thermal cycling deep inside the cylinder head wells. Over time, internal epoxy insulation breaks down, secondary copper windings experience micro-arcing, and dielectric boots degrade. Coupled with standard electrode erosion on factory plugs, this leads to weak spark delivery, hesitation under passing loads, poor fuel atomization, and intermittent P0300-P0306 diagnostic trouble codes.

The Engineering Solution

This comprehensive ignition service kit restores factory electrical impedance and flame-front propagation. Featuring heavy-duty silicone boots that resist dielectric puncture and heat-resistant electromagnetic windings, each coil delivers a consistent high-energy spark across the engine's Atkinson-cycle powerband. Paired with fine-wire laser-welded iridium spark plugs, this kit replaces OEM part number 273103L000 and interchange UF844, maintaining stable gap tolerances against high direct-injection cylinder pressures to maximize combustion stability under heavy loads.

Frequently Asked Questions

Does this fit the LX2 Palisade?
Yes, this is a direct fit for the 2020-2024 Hyundai Palisade equipped with the G6DN 3.8L V6 engine.

Are the iridium spark plugs pre-gapped for direct-injection operation?
Yes, the iridium plugs are calibrated to factory gap specifications for the Atkinson-cycle 3.8L, although checking gap clearance prior to installation is standard workshop practice.

The Hyundai Utility Standard

The LX2 chassis demands reliable low-end torque for cross-country cruising and rated 5,000-lb towing duty. Refreshing aging ignition components protects downstream catalytic converters from unburnt fuel while ensuring instantaneous throttle response under demanding payload demands.
