Direct-Fit Complete Ignition Service Kit for 2023-2024 Dodge Durango (WD)
What it Does: The complete ignition kit replaces worn factory coil packs and degraded spark plugs on the 2023-2024 Dodge Durango to eliminate secondary ignition misfires, stabilize idle quality, and restore peak combustion efficiency.
The Stock Dodge Durango Ignition System Thermal Degradation
The 5.7L HEMI Eagle architecture in the third-generation WD chassis utilizes a dual-plug-per-cylinder setup (16 plugs total across 8 cylinders) running tight clearances in high ambient heat. Over time, constant thermal cycling causes internal dielectric breakdown within the factory epoxy and secondary windings of the UF504 coil packs. Simultaneously, standard center electrodes suffer spark erosion, increasing the gap distance. This wider gap demands higher secondary firing voltages, straining weak coils, generating low-RPM stumble, and triggering intermittent P0300 multi-cylinder misfire fault codes under heavy throttle or towing loads.
The Engineering Solution
This full-service replacement kit pairs 8 high-output coil-on-plug units with 16 laser-welded NGK Platinum spark plugs. The ignition coils feature premium copper windings, internal silicon magnetic steel cores, and high-temp thermoplastic housings that resist thermal degradation and moisture intrusion. The platinum center electrodes minimize required firing voltage, providing stable electrical conductivity and superior resistance to fouling under sustained cylinder pressures. Replacing both coils and plugs simultaneously guarantees uniform resistance across all 8 cylinders and restores factory combustion timing.
What's Included
- 8 x Direct-Replacement Ignition Coils
- 16 x NGK Platinum Spark Plugs

Frequently Asked Questions & Fitment Warnings
Does this fit the WD Durango?
Yes, this is a direct fit for the 2023-2024 Dodge Durango equipped with the 5.7L HEMI V8 engine. It does not fit 3.6L Pentastar V6, 6.4L 392, or 6.2L Hellcat engine options.
What are the installation and torque recommendations?
Torque spark plugs to factory spec (13-15 lb-ft) into the aluminum head, apply dielectric grease inside the boots, and hand-snug coil hold-down bolts to avoid stripping brass intake inserts.
The Dodge Muscle Standard
Engineered to handle sustained high-load towing and aggressive acceleration cycles, this matched ignition set guarantees reliable, high-voltage spark delivery across all cylinders under severe operating conditions.
