Ignition Coil + Spark Plugs for Jeep Wagoneer (2022-2023) 5.7L

High-Dielectric Ignition Coil and Spark Plug Tune-Up Kit for 2022-2023 Jeep Wagoneer (WS)

What it Does: The ignition coil and spark plug kit restores secondary ignition voltage and combustion efficiency on the 2022-2023 Jeep Wagoneer to eliminate cylinder misfires, hesitation, and unburnt fuel cycles.

The Stock Jeep Wagoneer Ignition Degradation

The twin-spark architecture of the 5.7L HEMI platform subjects ignition components to intense thermal stress in the crowded engine bay of the WS chassis. Over time, engine bay heat soak degrades the internal epoxy encapsulation and copper windings inside the OEM coils. This leads to dielectric breakdown, secondary voltage leakage, and spark blowout under load. Coupled with gap erosion on aged plugs, this breakdown manifests as rough idling, hesitation under acceleration, poor fuel economy, and persistent misfire DTCs (P0300 through P0308).

The Engineering Solution

This service kit provides a complete ignition refresh utilizing 8 dual-terminal direct-fit ignition coils paired with 16 NGK Platinum spark plugs. The coils are manufactured with high-grade copper primary and secondary windings potted in vacuum-sealed epoxy to insulate against thermal breakdown and moisture intrusion. The NGK Platinum plugs feature a fine-wire center electrode and trivalent anti-corrosion plating, lowering required firing voltage, resisting carbon fouling, and ensuring rapid flame kernel propagation inside the hemispherical combustion chambers.

Frequently Asked Questions & Fitment Warnings

Does this fit the WS Wagoneer?

Yes, this is a direct fit for the 2022-2023 Jeep Wagoneer equipped with the 5.7L HEMI V8 engine. It does not fit Wagoneer models equipped with the 3.0L Hurricane Twin-Turbo inline-six or Grand Wagoneer 6.4L HEMI models.

Are secondary spark plug wires included in this package?

No, spark plug wires are not included; inspect and reuse your factory secondary plug leads or replace them separately if worn.

The Jeep Towing & Durability Standard

Full-size platforms like the Wagoneer demand flawless combustion when hauling heavy payloads or towing trailers over long grades. Refreshing your secondary ignition system with matching dual-output coils and platinum plugs maintains proper cylinder pressure, preserves catalytic converters, and delivers dependable V8 power under high mechanical strain.
