Over time, OEM epoxy insulation degrades and internal windings develop micro-fractures, while standard plugs experience gap erosion. This dielectric breakdown increases electrical resistance, causing weak spark discharge, erratic cold-start idling, hesitation under acceleration, and unburned fuel dumping into the exhaust stream.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive service kit features direct-fit coil packs built with premium-grade internal copper windings and reinforced thermoplastic housings to resist thermal fatigue and prevent high-voltage arcing. Paired with high-melting-point fine-wire iridium spark plugs, the system ensures lower voltage requirement for spark gap ionization, providing a robust flame kernel, stable idle, and maximized fuel atomization across the entire operating RPM 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;\"\u003e2011-2016 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;\"\u003e1.8L Nu MPi I4 \/ MD, UD\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;\"\u003e148 hp \/ 131 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;\"\u003eUF651, 27300-2E000, 273002E000, C1804, 5C1861, GN10633\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2011 Hyundai Elantra 1.8L L4 (GLS, Limited)\u003c\/li\u003e\n  \u003cli\u003e2012 Hyundai Elantra 1.8L L4 (GLS, Limited, Touring)\u003c\/li\u003e\n  \u003cli\u003e2013 Hyundai Elantra 1.8L L4 (GLS, Limited)\u003c\/li\u003e\n  \u003cli\u003e2014 Hyundai Elantra 1.8L L4 (SE, Limited)\u003c\/li\u003e\n  \u003cli\u003e2015 Hyundai Elantra 1.8L L4 (SE, Limited)\u003c\/li\u003e\n  \u003cli\u003e2016 Hyundai Elantra 1.8L L4 (SE, Limited, Value Edition)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Hyundai Commuter Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to withstand the demands of high-mileage daily commuting, this ignition setup clears common P0300-series misfire codes, restores peak stoichiometric efficiency, and guarantees dependable cold-weather start reliability.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50448294805752,"sku":"DS-EXT7NTYY5","price":69.95,"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-2011-2016-1-8l-1.jpg?v=1788638996","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-hyundai-elantra-2011-2016-1-8l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
