Over time, heat cycles break down the primary and secondary copper windings inside the OEM coils, degrading the internal dielectric epoxy potting. This creates internal arcing, high secondary resistance, and erratic spark delivery under heavy load. Compounding the issue, standard dual-plug electrode wear increases the required firing voltage, pushing aging ignition packs past their breakdown threshold and triggering stubborn P0300 through P0308 misfire codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit delivers 8 dual-output replacement coils paired with 16 twin-tip Denso spark plugs to refresh the entire high-voltage secondary ignition loop. Each coil is built with high-grade magnetic steel cores and high-temp epoxy encapsulation to prevent dielectric punch-through. Matched with platinum-alloy ground and center electrodes, the system maintains consistent arc stability under high cylinder pressures, preventing unburned hydrocarbon build-up and safeguarding downstream catalytic converters.\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;\"\u003e2003-2006 Mercedes Benz E-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\u003c\/strong\u003e (5.0L V8) \/ \u003cstrong\u003eW211\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\u003e0001587803\u003c\/strong\u003e, \u003cstrong\u003e0001587303\u003c\/strong\u003e, \u003cstrong\u003eA0001587803\u003c\/strong\u003e, \u003cstrong\u003eA0001587303\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\u003e2003-2006 Mercedes Benz E500 5.0L V8 (W211)\u003c\/li\u003e\n  \u003cli\u003e2004-2006 Mercedes Benz E500 4Matic 5.0L V8 (W211)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the W211 E-Class?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2003-2006 Mercedes Benz E-Class equipped with the \u003cstrong\u003eM113\u003c\/strong\u003e 5.0L engine.\u003c\/p\u003e\n\n\u003ch4\u003eWhy does this 8-cylinder engine require 16 spark plugs?\u003c\/h4\u003e\n\u003cp\u003eThe \u003cstrong\u003eM113\u003c\/strong\u003e V8 employs a factory twin-spark design with dual output coils to execute phased sequential ignition, which promotes cleaner burn cycles and prevents knock under varying engine loads.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mercedes Benz Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEuropean luxury powerplants demand exact spark timing and uncompromised electrical output.
