Constant heat cycling from the engine bay breaks down the internal epoxy potting and primary winding insulation over time. This insulation breakdown leads to primary voltage leaks, which manifest as rough idling, throttle hesitation under load, and stubborn P0300 to P0306 cylinder misfire trouble codes. Furthermore, as the original equipment platinum spark plugs wear down, their required firing voltage spikes dramatically. This increased electrical resistance places severe strain on already weakened factory ignition coils, degrading fuel economy and accelerating complete coil pack failure.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eTo combat W204 ignition failure, these replacement direct-fire coils utilize upgraded internal copper wire windings encased in high-grade thermal epoxy potting to resist engine bay heat soak and voltage blow-by. By delivering a more consistent, higher-energy spark, these coils eliminate load-based hesitation. The kit pairs these reinforced coils with advanced iridium spark plugs. Iridium's extreme melting point allows for a much finer wire center electrode, which drastically reduces the required firing voltage and yields a more concentrated, highly efficient spark front. This combined upgrade stabilizes idle vacuum, optimizes combustion efficiency, and completely restores factory torque output without triggering the Mercedes engine management unit's sensitive Check Engine Light parameters.\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;\"\u003e2010-2012 Mercedes Benz C-Class\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 2.5L 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;\"\u003e201 hp \/ 181 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, 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\u003e2010 Mercedes-Benz C250 2.5L V6\u003c\/li\u003e\n    \u003cli\u003e2011 Mercedes-Benz C250 2.5L V6\u003c\/li\u003e\n    \u003cli\u003e2012 Mercedes-Benz C250 2.5L V6\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Mercedes Benz Precision Standard\u003c\/h3\u003e\n  \u003cp\u003eEuropean engine management systems demand exacting electrical resistance values.
