As the OEM epoxy and internal windings break down from extended engine bay heat soak, electrical resistance increases, leading to weak spark delivery. This degradation causes the familiar Hemi shudder—rough idle, hard starting, and unburned fuel triggering misfire codes. Furthermore, standard factory spark plugs degrade quickly under heavy load, losing their precise electrode gap, which results in rapid carbon fouling and compromised fuel efficiency.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive 32-piece ignition kit directly addresses these thermal and electrical vulnerabilities. The upgraded ignition coils are wound with high-grade copper internal wire and sealed with advanced dielectric epoxy to resist heat soak and voltage leaks. This ensures a consistent, high-energy voltage transfer directly to the spark plug electrodes. Paired with superior Iridium spark plugs, the system benefits from a much higher melting point and superior shape retention compared to standard OE plugs. The dual-spark Hemi design relies on this concentrated, hotter spark to efficiently burn off combustion chamber deposits and prevent fouling. The included robust spark plug wires ensure zero voltage leakage, providing a direct, non-destructive replacement that restores factory power delivery, smooths out engine idle, and optimizes fuel consumption.\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;\"\u003e2005 Dodge Magnum\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;\"\u003e5.7L Hemi V8 (EZB) \/ LX\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;\"\u003e340 hp \/ 390 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;\"\u003eUF378, 56028394AB, 6987, ZFR6F-11G\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2005 Dodge Magnum 5.7L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Dodge Muscle Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt for the heavy demands of modern American muscle, this ignition overhaul ensures your Hemi V8 maintains relentless power delivery, immediate throttle response, and a smooth, commanding idle.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50064228417784,"sku":"DS-ES4NW6372","price":149.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-dodge-magnum-2005-5-7l-v8-1.webp?v=1785214628","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-iridium-spark-plugs-for-dodge-magnum-2005-5-7l-v8","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
