The factory coils suffer from severe thermal degradation due to their location directly atop the cylinder head, leading to micro-cracks in the internal epoxy housing. This structural failure results in voltage leakage, erratic idle, high-RPM misfires, and delayed throttle response. Furthermore, standard OEM spark plugs experience rapid gap erosion under high cylinder pressures, compromising the combustion event and significantly reducing both power output and engine efficiency.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis comprehensive ignition overhaul addresses the EA888's thermal shortcomings by utilizing premium, high-dielectric epoxy resin in the upgraded ignition coils to withstand extreme heat cycling and prevent voltage breakdown. Coupled with advanced high-performance Ruthenium spark plugs, this kit delivers superior ignitability. Ruthenium provides maximized oxidation resistance and a more concentrated spark kernel compared to traditional iridium or platinum plugs. This translates to complete combustion, eliminating spark blow-out under peak boost, smoothing out the idle, and maximizing the kinetic energy transferred to the piston. The result is consistent, reliable power delivery throughout the entire rev range.\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;\"\u003e2017-2020 Audi A4 \/ Quattro \/ allroad\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 Gen 3 2.0L TFSI \/ B9\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;\"\u003e252 hp \/ 273 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 (Alt: 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\u003e2017-2020 Audi A4 2.0L I4\u003c\/li\u003e\n    \u003cli\u003e2017-2020 Audi A4 Quattro 2.0L I4\u003c\/li\u003e\n    \u003cli\u003e2017-2020 Audi A4 allroad 2.0L I4\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe European Precision Standard\u003c\/h3\u003e\n  \u003cp\u003eThe precision engineering behind these replacement coils and ruthenium plugs ensures strict adherence to Audi's factory resistance specifications, guaranteeing a seamless installation with zero CEL (Check Engine Light) issues and smooth, misfire-free European performance.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48434931106040,"sku":"DS-EZLCHWH5P","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-a4-quattro-allroad-2017-2020-2-0l-i4-1.jpg?v=1779224355","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-spark-plugs-for-audi-a4-quattro-allroad-2017-2020-2-0l-i4","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
