Over time, the internal epoxy resin and factory copper windings break down, increasing electrical resistance. This degradation manifests as a weak spark, intermittent misfires under heavy engine load, rough idling, and reduced throttle response. As the primary coils fail, the factory spark plugs are forced to operate outside their optimal heat range, leading to rapid electrode wear, carbon fouling, and unburned fuel entering the exhaust stream, which can ultimately damage the catalytic converters.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit addresses the inherent design flaws of the factory ignition system by utilizing upgraded internal components. The replacement coils feature heavy-duty copper wire windings with superior dielectric insulation to resist high-voltage breakdown and mitigate heat soak in the tight V6 cylinder banks. Paired with laser-welded Iridium spark plugs, this system provides a concentrated, stable spark kernel that requires less primary voltage to jump the gap. The Iridium alloy construction offers extreme resistance to high-temperature corrosion and spark erosion, ensuring consistent timing, complete fuel atomization, and a smoother idle while preventing the dreaded blinking Check Engine Light (CEL).\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2008-2012 Mercedes Benz C-Class (C300 3.0L V6)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eM272 V6 \/ W204\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e228 hp \/ 221 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF535, 5C1748, 0001501980, 0001502680, 0001502780, 07C905\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2008 Mercedes-Benz C300 3.0L V6\u003c\/li\u003e\n  \u003cli\u003e2009 Mercedes-Benz C300 3.0L V6\u003c\/li\u003e\n  \u003cli\u003e2010 Mercedes-Benz C300 3.0L V6\u003c\/li\u003e\n  \u003cli\u003e2011 Mercedes-Benz C300 3.0L V6\u003c\/li\u003e\n  \u003cli\u003e2012 Mercedes-Benz C300 3.0L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Mercedes Benz Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet or exceed strict OE standards, this ignition kit ensures your W204 maintains the precise timing and smooth power delivery expected of a German luxury sedan, restoring reliable operation and keeping you free of misfire-related CELs.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50037210120440,"sku":"DS-E1PGWAAUY","price":109.95,"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-c300-2008-2012-3-0l-v6-1.jpg?v=1784755315","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-iridium-spark-plugs-for-mercedes-benz-c300-2008-2012-3-0l-v6","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
