Positioned directly inside the cylinder head, the factory coil packs endure severe heat cycling that gradually breaks down the internal epoxy potting. Over time, this degradation leads to micro-cracking in the housing, secondary voltage leaks, and inconsistent spark delivery. Combined with standard gap erosion on the factory spark plugs, the resulting weak electrical discharge causes incomplete fuel burn, sluggish throttle response, rough idling, and inevitable P0300-series misfire codes that trigger the Check Engine Light.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis ignition replacement kit resolves these inherent electrical weaknesses through upgraded internal materials and optimized coil windings. The updated coils feature high-temperature silicone boots and reinforced dielectric epoxy that resist heat soak and prevent voltage bleed-over to the engine block. High-grade primary and secondary copper windings ensure a strong, consistent voltage output even under heavy engine loads. Paired with the included performance Iridium spark plugs—which boast an ultra-fine center electrode for superior ignitability and a higher thermal threshold than standard platinum—this combination ensures optimal flame kernel propagation. The precise ignition timing improves fuel atomization, stabilizes the engine idle, restores lost horsepower, and efficiently reduces unburnt hydrocarbons.\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;\"\u003e2014-2020 Hyundai Tucson\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;\"\u003eNu 2.0L (G4NA\/G4NC) \/ LM \u0026amp; TL\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;\"\u003e164 hp \/ 151 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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2014 Hyundai Tucson 2.0L I4\u003c\/li\u003e\n  \u003cli\u003e2015 Hyundai Tucson 2.0L I4\u003c\/li\u003e\n  \u003cli\u003e2016 Hyundai Tucson 2.0L I4\u003c\/li\u003e\n  \u003cli\u003e2017 Hyundai Tucson 2.0L I4\u003c\/li\u003e\n  \u003cli\u003e2018 Hyundai Tucson 2.0L I4\u003c\/li\u003e\n  \u003cli\u003e2019 Hyundai Tucson 2.0L I4\u003c\/li\u003e\n  \u003cli\u003e2020 Hyundai Tucson 2.0L I4\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Hyundai Precision Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to meet and exceed stringent OEM electrical parameters, this direct-replacement ignition system ensures factory-like precision without the risk of ECU rejection, maximizing the reliability and efficiency of your daily driver.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48266908172536,"sku":"DS-EL9QW8J7G","price":134.95,"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-tucson-2014-2020-2-0l-i4-1.jpg?v=1776830990"},{"product_id":"ignition-coil-and-iridium-spark-plugs-for-hyundai-tucson-2005-2009-2-7l","title":"Ignition Coil and Iridium Spark Plugs for Hyundai Tucson (2005-2009) 2.7L","description":"\u003ch2\u003eDirect-Fit Ignition Coil and Iridium Spark Plug Kit for 2005-2009 Hyundai Tucson\u003c\/h2\u003e\n\n\u003cp\u003e\u003cstrong\u003eDirect-fit replacement:\u003c\/strong\u003e Restores complete combustion efficiency and eliminates cylinder misfires across the transverse 2.7L V6 powertrain by replacing tired ignition coils and worn plugs with high-dielectric components.\u003c\/p\u003e\n\n\u003ch3\u003eThe Stock Tucson Thermal Breakdown\u003c\/h3\u003e\n\u003cp\u003eFactory ignition coils on the 2.7L V6 operate in a tightly packaged engine bay subject to severe thermal cycling.
