Over time, OEM coil assemblies suffer dielectric breakdown from extreme thermal cycling, causing micro-fractures in the internal epoxy and weakening primary\/secondary copper windings. Simultaneously, factory spark plug electrodes erode, widening gaps and increasing secondary voltage demand. This degradation leads to unburnt fuel cycles, hesitation under load, reduced fuel efficiency, and P0300-P0304 misfire trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis ignition kit pairs four high-output coil-on-plug units with matched fine-wire iridium spark plugs for precise ignition synchronization. Engineered with high-conductivity copper windings, reinforced silicone boots, and heat-stabilized thermoplastic housings, each coil resists high-temperature degradation and voltage leakage. The ultra-fine iridium center electrodes ensure minimal firing voltage requirements, enhanced flame kernel propagation, and stable spark integrity under peak turbo boost pressures. Direct-fit blade terminals allow immediate plug-and-play installation.\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;\"\u003e2018-2020 Buick Regal TourX\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;\"\u003e2.0L LTG Turbo I4 \/ E2XX\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;\"\u003e250 hp \/ 295 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;\"\u003eUF680, UF-680, C869, C1827, 5C1884\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2018 Buick Regal TourX (Base, Preferred, Essence) 2.0L L4 Turbo Gas\u003c\/li\u003e\n  \u003cli\u003e2019 Buick Regal TourX (Base, Preferred, Essence) 2.0L L4 Turbo Gas\u003c\/li\u003e\n  \u003cli\u003e2020 Buick Regal TourX (Base, Preferred, Essence) 2.0L L4 Turbo Gas\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Buick Precision Benchmark\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet the exact diagnostic parameters of GM's direct-injected Ecotec platform, this kit maintains factory ECU spark mapping, ensures zero check-engine lights, and restores smooth throttle response across all driving conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50448489480440,"sku":"DS-EJYLTTK4X","price":100.95,"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-buick-regal-tourx-2018-2020-2-0l-1.jpg?v=1788647178","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-buick-regal-tourx-2018-2020-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
