Over time, engine bay thermal cycling degrades the factory coil-on-plug epoxy windings and hardens the silicone spark plug boots, leading to secondary voltage breakdown and micro-arcing. Simultaneously, cylinder pressures under turbo boost erode standard plug gaps, causing quenching, erratic combustion, high-load hesitations, and persistent P0300-P0304 diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis full tune-up assembly cures ignition failure through reinforced construction and optimized arc stability. The four replacement coil packs feature high-grade magnetic core laminations and premium vacuum-poured epoxy shielding to prevent internal arc blow-out under peak cylinder pressures. Paired with laser-welded fine-wire iridium spark plugs, this kit significantly lowers the ionization voltage threshold required to bridge the spark gap. The fine-wire iridium alloy resists spark erosion and high combustion-chamber temperatures, delivering consistent ignition timing and restoring fuel atomization efficiency across all four cylinders.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e4 Ignition Coils (Black, 4-Blade Connector)\u003c\/li\u003e\n  \u003cli\u003e4 Pre-Gapped Iridium Spark Plugs (12mm Thread, 14mm Hex, 25mm Reach)\u003c\/li\u003e\n\u003c\/ul\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;\"\u003e2016-2019 Buick Cascada\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 LWC Turbo \/ Delta II\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;\"\u003e200 hp \/ 207 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;\"\u003e55569253, 55595516, UF-821, UF821, 91970, ILNAR8B7G\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\u003e2016 Buick Cascada 1.6L L4 Turbo (Base, Premium)\u003c\/li\u003e\n  \u003cli\u003e2017 Buick Cascada 1.6L L4 Turbo (Base, Premium, Sport Touring)\u003c\/li\u003e\n  \u003cli\u003e2018 Buick Cascada 1.6L L4 Turbo (Base, Premium, Sport Touring)\u003c\/li\u003e\n  \u003cli\u003e2019 Buick Cascada 1.6L L4 Turbo (Base, Premium, Sport Touring)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the Delta II Cascada?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2016-2019 Buick Cascada equipped with the \u003cstrong\u003e1.6L LWC\u003c\/strong\u003e turbocharged inline-four engine.\u003c\/p\u003e\n\n\u003ch4\u003eDo the new spark plugs require gapping before installation?\u003c\/h4\u003e\n\u003cp\u003eNo, the iridium spark plugs come pre-gapped, though careful verification is recommended before torquing into the aluminum cylinder head.\u003c\/p\u003e\n\n\u003ch3\u003eThe Buick Calibration Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to satisfy GM European-derived architecture, this direct-fit ignition kit ensures precise signal synchronicity with the factory ECM to eliminate misfires, safeguard catalytic converters, and deliver smooth, factory-level open-top touring performance.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":68083580338424,"sku":"DS-ECFQ9WCV6","price":146.95,"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-cascada-2016-2019-1-6l-1.jpg?v=1794528782","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-buick-cascada-2016-2019-1-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
