Over time, the internal primary and secondary windings in the factory \u003cstrong\u003e273002GGA0\u003c\/strong\u003e coil packs experience dielectric breakdown, while the silicone spark plug boots harden and micro-crack. This causes high-voltage arc-over, secondary resistance spikes, and intermittent misfires under heavy acceleration. Concurrently, factory standard-electrode spark plugs suffer from premature gap erosion, increasing required breakdown voltage and compounding stress on the aging coils.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-fit overhaul kit combines high-dielectric epoxy-encapsulated ignition coils with fine-wire iridium spark plugs engineered to exceed OE durability thresholds. The coil assemblies utilize high-grade copper windings and premium magnetic silicon-steel cores to deliver consistent 30+ kV secondary output across all operating temperatures. Paired with laser-welded iridium-tipped spark plugs that feature an ultra-dense ceramic insulator, the kit maintains a stable spark kernel at lower firing voltages. This minimizes quenching effects, provides superior fouling resistance, and guarantees rapid flame propagation within direct-injection combustion chambers.\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;\"\u003e2016-2020 Kia Sorento\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;\"\u003e2.4L Theta II GDI (G4KJ) \/ UM\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;\"\u003e185 hp \/ 178 lb-ft\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;\"\u003eUF764, 273002GGA0, 93175, 5C2091, GN10730\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2016 Kia Sorento 2.4L L4 (L, LX)\u003c\/li\u003e\n  \u003cli\u003e2017 Kia Sorento 2.4L L4 (L, LX)\u003c\/li\u003e\n  \u003cli\u003e2018 Kia Sorento 2.4L L4 (L, LX)\u003c\/li\u003e\n  \u003cli\u003e2019 Kia Sorento 2.4L L4 (L, LX)\u003c\/li\u003e\n  \u003cli\u003e2020 Kia Sorento 2.4L L4 (L, LX)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the UM Sorento?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2016-2020 Kia Sorento equipped with the \u003cstrong\u003eTheta II GDI\u003c\/strong\u003e 2.4L engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShould I replace all four ignition coils and spark plugs simultaneously?\u003c\/strong\u003e\u003cbr\u003e Yes, replacing all coils and plugs as a set ensures uniform primary circuit resistance and prevents secondary cylinder imbalances across the ECU monitor.\u003c\/p\u003e\n\n\u003ch3\u003eThe Kia Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for everyday family utility and cross-country road trips, this ignition package restores dependable cold-start reliability and clean throttle response under high cabin payloads.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50623709806840,"sku":"DS-EL5OGC4LI","price":203.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-kia-sorento-2016-2020-2-4l-1.jpg?v=1790298586","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-iridium-spark-plugs-for-kia-sorento-2016-2020-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
