This degradation leads to high-voltage leakage, erratic spark discharge, and internal resistance spikes in the copper windings. Paired with eroded factory plug electrodes, this degradation causes rough cold starts, hesitation under throttle load, reduced fuel economy, and active P0300 through P0304 trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement ignition service pack utilizes heavy-duty primary and secondary copper windings insulated with high-grade thermal epoxy to prevent internal flashover and voltage loss. The matched iridium spark plugs feature ultra-fine center electrodes that require lower strike voltages while resisting carbon fouling and high combustion temperatures. High-tensile silicone boots shield against moisture intrusion and block spark arcing to the cylinder head.\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;\"\u003e2017-2021 GMC Acadia\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;\"\u003e2.5L LCV Ecotec \/ C1XX\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;\"\u003e193 hp \/ 188 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\u003e2017 GMC Acadia (SL, SLE) 2.5L L4 Gas\u003c\/li\u003e\n  \u003cli\u003e2018 GMC Acadia (SL, SLE) 2.5L L4 Gas\u003c\/li\u003e\n  \u003cli\u003e2019 GMC Acadia (SL, SLE) 2.5L L4 Gas\u003c\/li\u003e\n  \u003cli\u003e2020 GMC Acadia (SL, SLE) 2.5L L4 Gas\u003c\/li\u003e\n  \u003cli\u003e2021 GMC Acadia (SL, SLE) 2.5L L4 Gas\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe GMC Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM interface dimensions, this ignition system restores factory throttle response, smooth idle stability, and dependable cold-weather starting without triggering check engine lights or requiring PCM re-calibration.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50448483909880,"sku":"DS-EGDJRHQCG","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-gmc-acadia-2017-2021-2-5l-1.jpg?v=1788647056","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-gmc-acadia-2017-2021-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
