Ignition Coil and Iridium Spark Plugs for Nissan Armada (2017-2022) 5.6L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2017-2022 Nissan Armada

What it Does: The ignition coil and iridium spark plug kit replaces degraded factory ignition components on the 2017-2022 Armada to eliminate secondary voltage leakage, cure cylinder misfires, and restore combustion efficiency under load.

The Stock Nissan Armada Coil Thermal Breakdown and Electrode Erosion

The high-compression direct-injected VK56VD V8 engine places high electrical demands on the primary and secondary ignition circuits. Over extended thermal cycles, the factory pencil coils suffer epoxy insulation breakdown and internal winding degradation from high underhood temperatures. Simultaneously, the OEM spark plug ground electrodes erode, expanding the plug gap beyond tolerance. This forces the ignition coils to work against increased resistance, leading to spark scatter, hesitation under heavy acceleration, and intermittent P0300-P0308 misfire codes.

The Engineering Solution

This comprehensive tune-up kit features eight high-dielectric pencil ignition coils matched with fine-wire iridium spark plugs. The coils are engineered with heat-resistant copper primary and secondary windings potted in high-grade dielectric epoxy to stop internal arcing and voltage tracking. The included iridium spark plugs feature a laser-welded 0.6mm fine-wire center electrode and a platinum-tipped ground electrode. This metallurgical combination resists spark erosion, stabilizes idle quality, and requires lower ionization voltage to reliably fire high-pressure stoichiometric fuel mixtures.

Frequently Asked Questions

Does this fit the Y62 Armada?
Yes, this is a direct fit for the 2017-2022 Nissan Armada equipped with the VK56VD 5.6L V8 engine on the Y62 platform.

Do these spark plugs require gapping prior to installation?
No, the iridium spark plugs come pre-gapped to factory specifications; manual gapping is not recommended as it risks damaging the brittle fine-wire iridium electrode.

The Nissan Endurance Towing Caliber

When pulling heavy payloads or navigating rough backcountry grades, your Y62 Armada requires sustained, uninterrupted secondary voltage delivery. High combustion-chamber pressures during peak towing will instantly expose weak coils. Installing this matched coil-and-plug kit restores peak flame propagation and full-throttle towing dependability.
