Over time, internal epoxy insulation breaks down, leading to dielectric punch-through, secondary voltage degradation, and intermittent cylinder misfires (DTC P0300 through P0304). Furthermore, factory standard plugs suffer from electrode erosion and gap widening in the high-compression Atkinson-cycle \u003cstrong\u003eKappa II G4LE\u003c\/strong\u003e engine, causing hard switching between electric and internal combustion modes, degraded fuel economy, and unburnt hydrocarbon buildup.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis matched ignition refresh features four high-dielectric pencil ignition coils engineered to directly replace OEM numbers \u003cstrong\u003e2730103HA0\u003c\/strong\u003e and \u003cstrong\u003eUF843\u003c\/strong\u003e. Built with high-purity copper windings, high-grade silicon magnetic steel cores, and heat-resistant thermoplastic housings, these coils deliver consistent secondary energy to resist heat soak under heavy transient loads. Paired with fine-wire iridium-tipped spark plugs featuring trivalent metal plating to prevent corrosion and anti-fouling thermal insulators, the kit maintains a stable spark gap, prevents quench, and optimizes flame-front propagation during lean-burn Atkinson cycles.\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; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2017-2022 Hyundai Ioniq\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1.6L Kappa II (G4LE) \/ AE\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e104 hp \/ 109 lb-ft (Engine) | 139 hp \/ 195 lb-ft (System Combined)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2730103HA0, UF843\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2017-2022 Hyundai Ioniq Hybrid (Blue, SEL, Limited) 1.6L L4\u003c\/li\u003e\n  \u003cli\u003e2018-2022 Hyundai Ioniq Plug-in Hybrid PHEV (Base, SEL, Limited) 1.6L L4\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the AE Ioniq?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2017-2022 Hyundai Ioniq equipped with the 1.6L Kappa II G4LE engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre these spark plugs pre-gapped for the Atkinson hybrid engine?\u003c\/strong\u003e\u003cbr\u003e Yes, the iridium plugs arrive pre-gapped to factory Atkinson-cycle specifications for direct drop-in installation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Hyundai Hybrid Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet the stringent demands of high-efficiency Atkinson-cycle powertrains, this direct-fit ignition kit ensures smooth hybrid combustion transitions, zero CEL illumination, and factory-matched secondary coil output.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50593953874168,"sku":"DS-EPHX2KMXR","price":94.95,"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-ioniq-2017-2022-1-6l-1.jpg?v=1790054593","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-hyundai-ioniq-2017-2022-1-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
