Over time, thermal fatigue degrades the internal dielectric epoxy potting and copper winding insulation, causing high-voltage arcing, internal shorting, and coil degradation under sustained towing loads. In tandem, factory plug gap erosion increases secondary circuit resistance, overloading coil drivers and precipitating P0300-series misfire codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service kit features high-dielectric epoxy-potted coils engineered to prevent punch-through insulation breakdown under continuous thermal stress. Matched with sixteen fine-wire iridium center electrode spark plugs, this configuration reduces the required ionization voltage across the gap. The wear-resistant iridium alloy maintains precise spark gaps over extended operating intervals, ensuring optimal flame kernel propagation, stable combustion chamber pressures, and complete burn characteristics under heavy throttle load.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2011-2024 Ram 1500\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003e5.7L HEMI V8 (EZH \/ EZC)\u003c\/strong\u003e \/ \u003cstrong\u003eDS\u003c\/strong\u003e \u0026amp; \u003cstrong\u003eDT\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e395 hp \/ 410 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003e56029129AF\u003c\/strong\u003e, \u003cstrong\u003eUF504\u003c\/strong\u003e, \u003cstrong\u003e56029129AA\u003c\/strong\u003e, \u003cstrong\u003e56029129AB\u003c\/strong\u003e, \u003cstrong\u003e673-5202\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2011-2018 Ram 1500 5.7L HEMI V8 (\u003cstrong\u003eDS\u003c\/strong\u003e Chassis)\u003c\/li\u003e\n  \u003cli\u003e2019-2024 Ram 1500 Classic 5.7L HEMI V8 (\u003cstrong\u003eDS\u003c\/strong\u003e Chassis)\u003c\/li\u003e\n  \u003cli\u003e2019-2024 Ram 1500 5.7L HEMI V8 eTorque \/ Standard (\u003cstrong\u003eDT\u003c\/strong\u003e Chassis)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the DS and DT 1500?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2011-2024 Ram 1500 equipped with the \u003cstrong\u003e5.7L HEMI\u003c\/strong\u003e engine across both 4th and 5th generation platforms.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy are there 16 spark plugs for an 8-cylinder engine?\u003c\/strong\u003e\u003cbr\u003e The \u003cstrong\u003e5.7L HEMI\u003c\/strong\u003e cylinder head incorporates a twin-spark dual-plug architecture per cylinder to promote complete flame propagation and eliminate pre-ignition knock.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ram Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for severe duty cycles and sustained hauling, this ignition package delivers reliable arc stability to support maximum rated payload and towing capacity without voltage quenching.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50622920851704,"sku":"DS-E2OLK4X7Q","price":355.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-ram-1500-2011-2024-5-7l-1.jpg?v=1790276882","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-ram-1500-2011-2024-5-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
