High cylinder pressures and sustained heat degrade the internal secondary windings, causing intermittent spark loss, rough idling, hesitation under boost, and premature spark plug fouling due to weak flame front propagation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement ignition pack features primary and secondary windings wound with high-conductivity oxygen-free copper, sealed in high-dielectric epoxy potting to resist thermal degradation and electrical leakage. Paired with fine-wire iridium spark plugs engineered to withstand high boost conditions, the kit provides sustained spark energy, consistent high-voltage delivery through heavy-duty blade terminals, and reliable arc stability under heavy load.\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 Hyundai Elantra\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;\"\u003e1.4L Turbo GDI (Kappa II G4LD) \/ AD Chassis\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;\"\u003e128 hp \/ 156 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;\"\u003eUF857, UF-857, 2730103AA0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2017 Hyundai Elantra Eco 1.4L L4 Gas Turbo (G4LD)\u003c\/li\u003e\n  \u003cli\u003e2018 Hyundai Elantra Eco 1.4L L4 Gas Turbo (G4LD)\u003c\/li\u003e\n  \u003cli\u003e2019 Hyundai Elantra Eco 1.4L L4 Gas Turbo (G4LD)\u003c\/li\u003e\n  \u003cli\u003e2020 Hyundai Elantra Eco 1.4L L4 Gas Turbo (G4LD)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Hyundai Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM tolerances for direct plug-and-play installation, this complete ignition refresh maintains factory electrical resistance parameters, ensuring seamless ECU synchronization and zero check-engine lights across daily commuting and sustained highway driving.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50456039653624,"sku":"DS-EZ5HDAW8V","price":131.95,"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-hyundai-elantra-2017-2020-1-4l-1.jpg?v=1788757268","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-hyundai-elantra-2017-2020-1-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
