Over time, OEM ignition coils suffer from dielectric breakdown, internal copper winding fatigue, and micro-cracking along the epoxy insulation. Coupled with standard plug gap erosion, this causes spark blow-out under load, rough idle, poor cold-start combustion, and intermittent P0300-series misfire trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete 4-cylinder tune-up kit features high-grade copper primary and secondary windings encased in heat-resistant, high-dielectric epoxy housings for sustained spark energy. Matched with fine-wire iridium-tipped spark plugs, the assembly resists electrode quenching, lowers ignition voltage requirements, and maintains consistent flame kernel propagation under peak boost without carbon tracking or thermal fatigue.\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;\"\u003e2016-2019 Mercedes Benz GLC-Class (GLC300)\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;\"\u003eM274 2.0L Turbo \/ X253\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;\"\u003e241 hp \/ 273 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Numbers \/ Interchange\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF734, UF820, A2749060700, A2749061400, 2749060700, 2749061400, 28400714\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2016 Mercedes Benz GLC300 2.0L L4 (X253)\u003c\/li\u003e\n  \u003cli\u003e2017 Mercedes Benz GLC300 2.0L L4 (X253)\u003c\/li\u003e\n  \u003cli\u003e2018 Mercedes Benz GLC300 2.0L L4 (X253)\u003c\/li\u003e\n  \u003cli\u003e2019 Mercedes Benz GLC300 2.0L L4 (X253)\u003c\/li\u003e\n  \u003cli\u003e2017-2019 Mercedes Benz GLC300 4Matic 2.0L L4 (X253 \/ C253)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Mercedes Benz Precision Standard\u003c\/h3\u003e\n\u003cp\u003eCalibrated specifically for European direct-injection requirements, these components maintain precise dwell times and factory ECU signaling to eliminate check-engine lights while delivering smooth power transfer.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50448901308664,"sku":"DS-EE0DKVCKY","price":202.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-and-iridium-spark-plugs-for-mercedes-benz-glc-class-2016-2019-2-0l-1.jpg?v=1788662864","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-mercedes-benz-glc-class-2016-2019-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
