Over mileage and heat cycles, internal epoxy insulation develops micro-fractures, allowing high-voltage current to arc to ground rather than discharging across the plug gap. Coupled with standard factory plug electrode wear, the widened gap increases electrical resistance on the coils, leading to weak spark kernel development, cold-start stumbling, and under-load misfires.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement ignition pack upgrades the system using heavy-duty internal copper windings encapsulated in high-dielectric epoxy resin to prevent voltage punch-through under high combustion pressures. Paired with fine-wire iridium spark plugs engineered with high thermal capacity, this assembly lowers the ionization voltage required for ignition, ensures precise flame front propagation, and resists carbon fouling during extended idle and towing conditions.\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;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2002-2008 Dodge Ram 1500\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e3.7L PowerTech V6 (EKG) \/ DR \/ DH Chassis\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e215 hp \/ 235 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF270, UF-270, 56028138, 56028138AB, 56028138AD, UF297, UF399, ZFR6FGP, 56028138AE, 56028138AF, 52-2034, 5C1114, E232, 178-8483\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2002-2008 Dodge Ram 1500 3.7L V6 (ST, SLT, Tradesman Trims)\u003c\/li\u003e\n  \u003cli\u003eDirect OE Interchange: UF270, UF-270, UF297, UF399, 56028138, 56028138AB, 56028138AD, 56028138AE, 56028138AF, 52-2034, 5C1114, E232, 178-8483, ZFR6FGP\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Dodge Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle severe thermal and vibrational stress during heavy bed loads and towing, this ignition rebuild maintains steady combustion timing and reliable power delivery across all operational demands.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50451864223992,"sku":"DS-EPHY2G4ZW","price":81.95,"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-dodge-ram-1500-2002-2008-3-7l-1.jpg?v=1788711668","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-dodge-ram-1500-2002-2008-3-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
