Over time, the internal windings break down due to extreme engine bay heat soak, leading to weak spark propagation. This weakness manifests as rough idling, hesitation under heavy throttle, and dreaded cylinder misfire codes. Furthermore, standard OEM spark plug electrodes wear down rapidly under the intense cylinder pressures of the turbocharged 1.8L and 2.0L powerplants, compromising combustion efficiency and robbing the engine of potential power and fuel economy.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis comprehensive ignition kit resolves factory misfire issues by combining high-output ignition coils with premium high-performance ruthenium spark plugs. The upgraded coils feature enhanced primary and secondary copper windings, insulated with high-dielectric epoxy to withstand extreme thermal cycling and resist voltage leaks. This ensures a significantly stronger, more stable spark output. Paired with the cutting-edge ruthenium spark plugs—which offer superior durability and melting resistance compared to traditional iridium or platinum—this system guarantees optimal ignition timing and complete fuel burn. The resulting synergy provides smoother acceleration, restored throttle response, and robust reliability for both daily driven and performance-tuned EA888 engines.\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;\"\u003e2015-2020 Audi A3, A3 Quattro, S3\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;\"\u003eEA888 \/ 8V\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;\"\u003e170-292 hp \/ 200-280 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;\"\u003eIC780565710478109512504 (Interchange: UF765, UF716, C1847)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2015-2020 Audi A3 1.8L I4\u003c\/li\u003e\n    \u003cli\u003e2015-2020 Audi A3 2.0L I4\u003c\/li\u003e\n    \u003cli\u003e2015-2020 Audi A3 Quattro 2.0L I4\u003c\/li\u003e\n    \u003cli\u003e2015-2020 Audi S3 2.0L I4\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Audi Precision Standard\u003c\/h3\u003e\n  \u003cp\u003eEngineered to meet the exact demands of European tuning, this kit ensures a perfect fit, OEM-level electrical precision, and a smooth, check-engine-light-free driving experience.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48434920685816,"sku":"DS-E6XZ96P8O","price":189.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-audi-a3-quattro-s3-2015-2020-1-8l-2-0l-i4-1.jpg?v=1779224310","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-spark-plugs-for-audi-a3-quattro-s3-2015-2020-1-8l-2-0l-i4","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
