Over time, factory ignition coils suffer from internal thermal breakdown, degrading the internal copper windings and cracking the silicone boots. This dielectric fatigue, combined with gap erosion on aged factory spark plugs, increases resistance across the secondary ignition circuit. The result is erratic spark delivery, cold-start hesitation, rough idle, increased fuel consumption, and high-boost misfires under load that trigger CEL fault codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement ignition tune-up kit features four coil-on-plug units engineered with high-conductivity copper windings and high-grade epoxy encapsulation to resist thermal degradation and internal shorting. Matched with four fine-wire iridium spark plugs, this setup delivers a focused, stable spark kernel capable of withstanding dense direct-injected fuel charges. Direct-fit blade connectors ensure seamless integration with the factory wiring harness without signal distortion.\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;\"\u003e2014-2019 Mercedes Benz CLA-Class (2.0L L4 Turbo)\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;\"\u003eM270 \/ C117\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;\"\u003e208 hp \/ 258 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number \/ 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\u003e2014-2019 Mercedes-Benz CLA250 Base 2.0L L4 Turbocharged (C117)\u003c\/li\u003e\n  \u003cli\u003e2014-2019 Mercedes-Benz CLA250 4Matic 2.0L L4 Turbocharged (C117)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Mercedes Benz Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact European diagnostic tolerances, this ignition service kit maintains precise resistance values required by the Mercedes-Benz Bosch\/Delphi engine management systems, ensuring clean combustion cycles without false knock detection or Check Engine Lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50448900489464,"sku":"DS-EP2C1RPDJ","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-cla-class-2014-2019-2-0l-1.jpg?v=1788662836","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-mercedes-benz-cla-class-2014-2019-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
