Factory ignition coils deteriorate over time due to severe thermal cycling trapped inside the hot V configuration, degrading the internal copper windings and cracking the epoxy resin potting. Concurrently, factory spark plug gaps expand as electrode erosion occurs under elevated boost levels. This combination results in spark blowout, rough cold-start idling, unburned hydrocarbon buildup, and diagnostic trouble codes such as P0300 through P0308 under heavy load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition service package restores combustion integrity using 8 high-output coil-on-plug units paired with pre-gapped double iridium spark plugs. The ignition coils utilize premium magnetic core laminations and high-temperature silicone boots rated to resist dielectric punch-through past 35kV. Matching them with fine-wire iridium center electrodes and platinum ground pads reduces the required firing voltage, providing consistent flame kernel development across all boost thresholds without taxing the factory ECU drivers.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e2013-2016 Mercedes Benz G-Class\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\u003eM157 5.5L Biturbo V8\u003c\/strong\u003e \/ \u003cstrong\u003eW463\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;\"\u003e536 hp \/ 561 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\u003eUF741\u003c\/strong\u003e, \u003cstrong\u003eA2769063700\u003c\/strong\u003e, \u003cstrong\u003e2769063700\u003c\/strong\u003e, \u003cstrong\u003e2769060501\u003c\/strong\u003e, \u003cstrong\u003e0040103070\u003c\/strong\u003e, \u003cstrong\u003eZR6SII3320\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2013 Mercedes Benz G-Class G63 AMG 5.5L V8 Biturbo (M157)\u003c\/li\u003e\n  \u003cli\u003e2014 Mercedes Benz G-Class G63 AMG 5.5L V8 Biturbo (M157)\u003c\/li\u003e\n  \u003cli\u003e2015 Mercedes Benz G-Class G63 AMG 5.5L V8 Biturbo (M157)\u003c\/li\u003e\n  \u003cli\u003e2016 Mercedes Benz G-Class G63 AMG 5.5L V8 Biturbo (M157)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the W463 G-Class?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2013-2016 Mercedes Benz G-Class equipped with the \u003cstrong\u003eM157\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShould spark plugs and ignition coils be replaced at the same interval on the M157?\u003c\/strong\u003e\u003cbr\u003e Yes, replacing both components simultaneously prevents worn plugs from overloading new coils and eliminates secondary misfire diagnosis cycles.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mercedes Benz Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet stringent European performance thresholds, this kit ensures complete diagnostic compliance with zero check-engine lights while maintaining peak twin-turbocharged V8 delivery.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50625856504056,"sku":"DS-E5HIOD16G","price":499.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-mercedes-benz-g-class-2013-2016-5-5l-1.jpg?v=1790352428","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-mercedes-benz-g-class-2013-2016-5-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
