The replacement coils feature reinforced copper primary and secondary windings potted in high-grade heat-resistant epoxy to resist breakdown caused by underhood thermal saturation. Coupled with ultra-fine wire iridium center electrodes, this package requires significantly less secondary firing voltage to bridge the gap, preventing high-RPM spark blowout and providing stable combustion throughout the powerband.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e2019-2020 Hyundai Santa Fe\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;\"\u003e\n\u003cstrong\u003e2.4L Theta II G4KJ\u003c\/strong\u003e \/ \u003cstrong\u003eTM\u003c\/strong\u003e\n\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;\"\u003e\n\u003cstrong\u003e27300-2GGA0\u003c\/strong\u003e, \u003cstrong\u003eUF764\u003c\/strong\u003e, \u003cstrong\u003e93175\u003c\/strong\u003e, 5C2091, GN10730\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2019 Hyundai Santa Fe 2.4L (SE, SEL, SEL Plus)\u003c\/li\u003e\n  \u003cli\u003e2020 Hyundai Santa Fe 2.4L (SE, SEL)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the TM Santa Fe?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2019-2020 Hyundai Santa Fe equipped with the \u003cstrong\u003e2.4L Theta II G4KJ\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eShould spark plugs and coil packs be replaced at the same time?\u003c\/h4\u003e\n\u003cp\u003eYes, pairing new ignition coils with fresh iridium plugs ensures consistent primary-to-secondary resistance and prevents old, high-resistance plugs from prematurely killing new coil windings.\u003c\/p\u003e\n\n\u003ch3\u003eThe Hyundai Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet precise OE resistance specifications, this direct-fit ignition tune-up assembly restores clean burning cycles, reliable cold-start crank performance, and long-term drivetrain dependability for your daily cross-town commute or family highway travel.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67524635361528,"sku":"DS-E9YOCN9C2","price":205.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-hyundai-santa-fe-2019-2020-2-4l-1.jpg?v=1790460909"}],"url":"https:\/\/performancechiptuning.com\/collections\/hyundai-santa-fe-ignition.oembed","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
