Over thermal cycles within the tightly packaged \u003cstrong\u003eC215\u003c\/strong\u003e engine bay, factory coil packs suffer internal epoxy insulation breakdown and primary-to-secondary winding short circuits. Combined with widening electrode gaps on worn standard plugs, resistance climbs dramatically. This thermal fatigue leads to intermittent secondary breakdown under load, rough idle, unburned hydrocarbon buildup, and recurring P0300-P0308 multi-cylinder misfire codes that trigger limp mode.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service kit replaces all failure-prone ignition components with eight high-output dual-tower coil packs and sixteen pre-gapped \u003cstrong\u003eNGK Iridium IX (BKR5EIX-11)\u003c\/strong\u003e plugs. The coils feature reinforced PBT housings and high-temperature vacuum-poured epoxy to prevent dielectric punch-through under high under-hood heat soak. Paired with ultra-fine 0.6mm laser-welded iridium center electrodes, this configuration requires lower ionization voltage, promotes immediate quenching resistance, and maintains razor-sharp flame kernel development across the twin-plug combustion chamber.\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: solid font-size: min-width:\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;\"\u003e2000-2006 Mercedes Benz CL-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\u003eM113.960 5.0L V8\u003c\/strong\u003e \/ \u003cstrong\u003eC215\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;\"\u003e302 hp \/ 339 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\u003eUF359\u003c\/strong\u003e, \u003cstrong\u003e5C1434\u003c\/strong\u003e, \u003cstrong\u003eE389\u003c\/strong\u003e, \u003cstrong\u003e52-1776\u003c\/strong\u003e, \u003cstrong\u003e5098138AA\u003c\/strong\u003e, \u003cstrong\u003eIC489\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\u003e2000 Mercedes Benz CL-Class CL500 5.0L V8 (C215 \/ M113)\u003c\/li\u003e\n  \u003cli\u003e2001 Mercedes Benz CL-Class CL500 5.0L V8 (C215 \/ M113)\u003c\/li\u003e\n  \u003cli\u003e2002 Mercedes Benz CL-Class CL500 5.0L V8 (C215 \/ M113)\u003c\/li\u003e\n  \u003cli\u003e2003 Mercedes Benz CL-Class CL500 5.0L V8 (C215 \/ M113)\u003c\/li\u003e\n  \u003cli\u003e2004 Mercedes Benz CL-Class CL500 5.0L V8 (C215 \/ M113)\u003c\/li\u003e\n  \u003cli\u003e2005 Mercedes Benz CL-Class CL500 5.0L V8 (C215 \/ M113)\u003c\/li\u003e\n  \u003cli\u003e2006 Mercedes Benz CL-Class CL500 5.0L V8 (C215 \/ M113)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the C215 CL-Class?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2000-2006 Mercedes Benz CL-Class equipped with the \u003cstrong\u003eM113\u003c\/strong\u003e 5.0L twin-spark engine.\u003c\/p\u003e\n\n\u003ch4\u003eAre spark plug wires included in this service pack?\u003c\/h4\u003e\n\u003cp\u003eNo, this kit supplies the 8 dual-lead coils and 16 NGK iridium spark plugs; reusable factory secondary leads or new direct-fit wire sets must be utilized.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mercedes Benz Precision Standard\u003c\/h3\u003e\n\u003cp\u003ePreserve factory German driveability and prevent nuisance check engine lights by renewing all twin-spark combustion components simultaneously to OE-level impedance specifications.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67524642308344,"sku":"DS-EQNBPQPKX","price":409.95,"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-cl-class-2000-2006-5-0l-1.jpg?v=1790461122","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-iridium-spark-plugs-for-mercedes-benz-cl-class-2000-2006-5-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
