Over prolonged runtime, heat soak deteriorates the internal copper winding insulation and dielectric epoxy potting, leading to micro-arcing and secondary voltage drop under load. Compounding this issue, factory spark plug ground electrodes erode, expanding the gap and demanding higher secondary breakdown voltages. This causes random misfires (DTC P0300–P0306), unburnt fuel fouling the catalytic converters, and diminished fuel economy.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service kit features reinforced coil-on-plug units wound with high-conductivity copper wire and sealed with high-dielectric epoxy to withstand extreme engine bay heat without shorting. The included spark plugs feature laser-welded, fine-wire iridium center electrodes and platinum-tipped ground pads, lowering the required strike voltage, resisting spark erosion, and ensuring immediate flame kernel expansion across all load ranges.\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;\"\u003e2013-2018 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\u003e3.6L Pentastar V6\u003c\/strong\u003e \/ \u003cstrong\u003eDS\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;\"\u003e305 hp \/ 269 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\u003eUF648\u003c\/strong\u003e, \u003cstrong\u003e51491685AH\u003c\/strong\u003e, \u003cstrong\u003e51491685AI\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\u003e2013-2018 Ram 1500 Tradesman 3.6L V6\u003c\/li\u003e\n  \u003cli\u003e2013-2018 Ram 1500 SLT 3.6L V6\u003c\/li\u003e\n  \u003cli\u003e2013-2018 Ram 1500 HFE 3.6L V6\u003c\/li\u003e\n  \u003cli\u003e2014-2018 Ram 1500 Big Horn \/ Lone Star 3.6L V6\u003c\/li\u003e\n  \u003cli\u003e2014-2018 Ram 1500 Express 3.6L V6\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 2013-2018 Ram 1500 equipped with the \u003cstrong\u003e3.6L Pentastar V6\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo these iridium spark plugs require manual gapping before installation?\u003c\/strong\u003e\u003cbr\u003e No, these plugs come pre-gapped from the factory, and mechanical gapping tools should not be used on fine-wire iridium tips to avoid brittle fractures.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ram Workhorse Caliber\u003c\/h3\u003e\n\u003cp\u003eTowing and hauling require uninterrupted torque from the \u003cstrong\u003eDS\u003c\/strong\u003e platform.
