The internal copper windings develop micro-fractures, and the silicone spark plug boots harden and glaze, allowing high-voltage spark leakage to earth rather than bridging the plug gap. Coupled with standard copper core spark plugs that suffer from rapid electrode erosion and widening gaps under heat soak, the \u003cstrong\u003e4.7L PowerTech V8\u003c\/strong\u003e experiences intermittent misfires (P0300 through P0308 codes), hesitant acceleration, and increased unburnt hydrocarbon emissions.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete tune-up kit features heavy-duty coil-on-plug pencil coils paired with fine-wire iridium spark plugs engineered to resist thermal degradation. The coils utilize premium insulated copper wire and high-dielectric epoxy potting to prevent internal voltage arcing under high-demand operation. Each coil features an integrated heat-resistant fluorosilicone boot that maintains an airtight seal against the cylinder head spark plug tube. The accompanying iridium spark plugs utilize laser-welded, ultra-fine 0.6mm iridium center electrodes with high-purity alumina ceramic insulators. This metallurgy lowers required ignition voltage, delivers a more focused spark kernel for complete fuel atomization, and resists carbon fouling far longer than standard nickel-alloy plugs.\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;\"\u003e2011-2013 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;\"\u003e4.7L PowerTech V8 \/ DS\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;\"\u003e310 hp \/ 330 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\u003e5149049AB\u003c\/strong\u003e, \u003cstrong\u003eUF601\u003c\/strong\u003e, \u003cstrong\u003eU4042\u003c\/strong\u003e, \u003cstrong\u003e48937\u003c\/strong\u003e, \u003cstrong\u003eC755\u003c\/strong\u003e, \u003cstrong\u003eCUF601\u003c\/strong\u003e, \u003cstrong\u003eC1649\u003c\/strong\u003e, \u003cstrong\u003e5C1706\u003c\/strong\u003e, \u003cstrong\u003eGN10458\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 Ram 1500 4.7L V8 (Tradesman, ST, SLT)\u003c\/li\u003e\n  \u003cli\u003e2012 Ram 1500 4.7L V8 (Tradesman, ST, SLT)\u003c\/li\u003e\n  \u003cli\u003e2013 Ram 1500 4.7L V8 (Tradesman, SLT, HFE)\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 1500?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2011-2013 Ram 1500 equipped with the \u003cstrong\u003e4.7L PowerTech V8\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre these spark plugs pre-gapped for installation?\u003c\/strong\u003e\u003cbr\u003e While pre-gapped at the factory, always verify the spark plug gap against OEM service manual specifications prior to installation, using caution to avoid damaging the fine iridium tip.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ram Heavy-Duty Work Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for sustained hauling and demanding payload duties, this complete ignition refresh restores smooth idle characteristics, crisp throttle response, and reliable cold-crank ignition under heavy work truck operating conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50603782832376,"sku":"DS-EB28E0A0U","price":154.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-and-iridium-spark-plugs-for-ram-1500-2011-2013-4-7l-1.jpg?v=1790088396","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-ram-1500-2011-2013-4-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
