<h2 style="font-size: clamp(18px, 3vw, 21px); margin-bottom: 15px; line-height: 1.3;">Direct-Fit Complete Ignition Service Kit for 2023-2024 Dodge Durango (WD)</h2> <p><strong>What it Does:</strong> 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.</p> <h3>The Stock Dodge Durango Ignition System Thermal Degradation</h3> <p>The <strong>5.7L HEMI Eagle</strong> architecture in the third-generation <strong>WD</strong> 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 <strong>UF504</strong> 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.</p> <h3>The Engineering Solution</h3> <p>This full-service replacement kit pairs 8 high-output coil-on-plug units with 16 laser-welded <strong>NGK</strong> 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 is designed to ensure uniform resistance across all 8 cylinders and restores factory combustion timing.</p> <h3>What's Included</h3> <ul> <li>8 x Direct-Replacement Ignition Coils</li> <li>16 x NGK Platinum Spark Plugs</li> </ul> <h3>Technical Specifications</h3> <div style="overflow-x: auto; margin-bottom: 20px;"> <table width="100% style=" border-collapse: collapse border: solid font-size: min-width:> <tr style="background-color: #f9f9f9;"> <th style="padding:10px; text-align: left; border: 1px solid #e0e0e0;">Fitment</th> <td style="padding:10px; border: 1px solid #e0e0e0;">2023-2024 Dodge Durango</td> </tr> <tr> <th style="padding:10px; text-align: left; border: 1px solid #e0e0e0;">Engine / Chassis</th> <td style="padding:10px; border: 1px solid #e0e0e0;">5.7L HEMI V8 (EZH) / WD</td> </tr> <tr style="background-color: #f9f9f9;"> <th style="padding:10px; text-align: left; border: 1px solid #e0e0e0;">Stock Output</th> <td style="padding:10px; border: 1px solid #e0e0e0;">360 hp / 390 lb-ft</td> </tr> <tr> <th style="padding:10px; text-align: left; border: 1px solid #e0e0e0;">Replaces OEM Part #</th> <td style="padding:10px; border: 1px solid #e0e0e0;">UF504, 5018, 26C1027, V33-70-0011, SKIC102, CUF504, C1526VC, 2IGC0173, 673-5202, 52-1828, C1526SPEC, EBC1007, 140038-8, 140038K, 140038K-8, 2IC405, 50090, 36-8121, 2505-302202, IGC0164, E1004, 5602129AA, 56029129AA, 56029129AB, 56029129AF, GN10352, 8255, 82553, 48716, U5121, C-693, 140038, 68060346AA, 68238603AA, C1526, 2-50090, 921-2093, 5C1569</td> </tr> </table> </div> <h3>Compatibility</h3> <ul> <li>2023 Dodge Durango 5.7L V8 (R/T, Citadel)</li> <li>2024 Dodge Durango 5.7L V8 (R/T, Citadel)</li> </ul> <h3>Frequently Asked Questions & Fitment Warnings</h3> <h4>Does this fit the WD Durango?</h4> <p>Yes, this is a direct fit for the 2023-2024 Dodge Durango equipped with the <strong>5.7L HEMI</strong> V8 engine.
