Over continuous heat-soak cycles, the factory ignition coil epoxy potting and dielectric rubber boots harden, crack, and micro-arc against the cylinder head bores. This internal voltage dissipation causes secondary ignition collapse, fouled spark plugs, sluggish throttle response, and persistent misfire trouble codes (P0300–P0308) under heavy open-throttle load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit restores factory-rated spark energy using eight matched coil-on-plug units and eight NGK G-Power platinum-tipped spark plugs. The ignition coils feature high-permeability magnetic silicon steel cores and high-grade copper windings insulated with premium epoxy resin to withstand extreme engine bay heat without dielectric breakdown. Paired with fine-wire platinum center electrodes, this set ensures a stable arc, uniform flame front propagation, and rapid throttle response while directly superseding OEM part numbers \u003cstrong\u003e0001501980\u003c\/strong\u003e, \u003cstrong\u003e0001502680\u003c\/strong\u003e, and \u003cstrong\u003e2729060060\u003c\/strong\u003e.\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;\"\u003e2007-2010 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;\"\u003eM273 \/ C216\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;\"\u003eUF535, 0001501980, 0001502680, 0001502780, 2729060060\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\u003e2007-2010 Mercedes Benz CL-Class CL550 Base 5.5L V8 (M273)\u003c\/li\u003e\n  \u003cli\u003e2009-2010 Mercedes Benz CL-Class CL550 4Matic 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 C216 CL-Class?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2007-2010 Mercedes Benz CL-Class equipped with the M273 engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo these spark plugs require pre-gapping before installation?\u003c\/strong\u003e\u003cbr\u003e These NGK spark plugs arrive pre-gapped, though verifying the factory 0.031-inch gap before final torque installation is recommended service practice.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mercedes Benz Precision Standard\u003c\/h3\u003e\n\u003cp\u003eCalibrated specifically for European electronic engine management, these matched ignition components maintain exact primary and secondary resistance values to guarantee smooth power delivery without triggering false CEL misfire codes.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50625826881784,"sku":"DS-EH1N9UV2P","price":248.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-mercedes-benz-cl-class-2007-2010-5-5l-1.jpg?v=1790352040","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-spark-plugs-for-mercedes-benz-cl-class-2007-2010-5-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
