Positioned directly atop the cylinder head, they endure constant heat soak cycles, leading to the breakdown of internal winding resistance and deterioration of the epoxy potting. Over time, this manifests as weak spark output, intermittent cylinder misfires under heavy load, and a deteriorating idle quality. Furthermore, as the factory spark plugs wear past 60,000 miles, the electrode gap widens, forcing the aging ignition coils to work harder to bridge the gap. This elevated electrical workload accelerates coil failure, ultimately resulting in reduced fuel economy, sluggish throttle response, and an illuminated Check Engine Light (CEL) indicating active P0300-series misfire codes.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eUpgrading to this combined ignition coil and iridium spark plug kit comprehensively addresses these thermal and electrical shortcomings. The replacement coils feature high-grade copper internal windings and advanced high-dielectric epoxy potting, effectively isolating the primary and secondary circuits from severe engine bay heat to prevent voltage leaks. This ensures consistent, high-voltage energy transfer across the entire RPM range. Paired with performance iridium spark plugs, the system benefits from an ultra-fine center electrode that requires significantly less voltage to fire while providing a more concentrated, robust spark kernel. Iridium's exceptional melting point resists gap erosion, guaranteeing a complete and efficient fuel burn. The result is restored horsepower, smoother acceleration, and long-term reliability without the risk of premature coil burnout.\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;\"\u003e2012-2020 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;\"\u003e1.8L Nu G4NB, 2.0L Nu G4NA \/ MD, JK, GD, AD, PD\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;\"\u003e147-173 hp \/ 131-154 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 \/ 273002E000 \/ IC780521660478109317504\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2012-2020 Hyundai Elantra (1.8L \u0026amp; 2.0L I4)\u003c\/li\u003e\n    \u003cli\u003e2013-2014 Hyundai Elantra Coupe (1.8L \u0026amp; 2.0L I4)\u003c\/li\u003e\n    \u003cli\u003e2013-2020 Hyundai Elantra GT (1.8L \u0026amp; 2.0L I4)\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Hyundai Reliability Standard\u003c\/h3\u003e\n  \u003cp\u003eFor the KDM daily driver, maintaining optimal spark delivery is critical for long-term engine health.
