Over time, heat soak degrades the internal epoxy potting and secondary copper windings of the factory coils, leading to internal shorting, micro-arcing, and intermittent voltage loss. Simultaneously, OEM spark plugs experience electrode erosion and gap enlargement, increasing the ionization voltage required to bridge the gap. This excessive resistance overburdens aging coil windings, resulting in rough running conditions, sluggish throttle response, reduced fuel economy, and persistent P0300 through P0308 cylinder misfire codes stored in the ECU.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition tune-up kit restores high-voltage delivery using eight direct-fit ignition coils built to OE specifications alongside matched NGK G-Power platinum spark plugs (\u003cstrong\u003eLKR7BGP \/ 95983\u003c\/strong\u003e). The coils feature high-grade magnetic silicon steel cores and temperature-resistant silicone boots to resist dielectric puncture and seal out moisture. Paired with fine-wire platinum center electrodes, this package lowers required firing voltage, provides rapid flame propagation, and ensures reliable ignition under heavy load. Replacing all eight cylinders simultaneously balances electrical resistance across both cylinder banks of the \u003cstrong\u003eM273\u003c\/strong\u003e, restoring smooth operation and factory power delivery.\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;\"\u003e2007-2011 Mercedes Benz CLS-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;\"\u003eM273 5.5L V8 \/ W219\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;\"\u003e382 hp \/ 391 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;\"\u003e0001501980, 0001502680, 0001502780, 2729060060, UF535\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\u003e2007-2011 Mercedes Benz CLS-Class CLS550 5.5L V8 (M273)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the W219 CLS-Class?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2007-2011 Mercedes Benz CLS-Class equipped with the M273 5.5L V8 engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the recommended installation torque for the spark plugs?\u003c\/strong\u003e\u003cbr\u003e Torque the spark plugs to the factory specification of 20 to 25 Nm (15 to 18 lb-ft) into clean, dry cylinder head threads.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mercedes Benz Precision Caliber\u003c\/h3\u003e\n\u003cp\u003eEuropean high-compression powertrains require exact secondary ignition voltages to avoid misfire detection and unburned fuel entering catalytic converters.
