This thermal stress causes secondary winding resistance drift, resulting in voltage leakage, rough idle, hesitation under load, and intermittent P0300-P0304 misfire diagnostic trouble codes. Concurrently, factory plugs suffer electrode erosion, widening the spark gap and overworking the coils.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive kit provides four coil packs wound with high-conductivity oxygen-free copper and insulated with high-grade epoxy resin to prevent dielectric puncture under high-temperature cylinder-head conditions. Paired with four fine-wire iridium spark plugs, this setup ensures lower required firing voltage, precise flame kernel formation, and stable combustion across the entire RPM band. The direct-fit blade connectors and boots resist ozone and thermal cracking, restoring immediate throttle response and efficient fuel burn.\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;\"\u003e2015-2021 Chevrolet Colorado\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 I4 \/ GMT 700\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;\"\u003e200 hp \/ 191 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, 12654078, 12627120, 12652400, C869, C1827, 5C1884, GN10682\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2015 Chevrolet Colorado 2.5L L4 Base, WT, LT\u003c\/li\u003e\n  \u003cli\u003e2016 Chevrolet Colorado 2.5L L4 Base, WT, LT\u003c\/li\u003e\n  \u003cli\u003e2017 Chevrolet Colorado 2.5L L4 Base, WT, LT\u003c\/li\u003e\n  \u003cli\u003e2018 Chevrolet Colorado 2.5L L4 Base, WT, LT\u003c\/li\u003e\n  \u003cli\u003e2019 Chevrolet Colorado 2.5L L4 Base, WT, LT\u003c\/li\u003e\n  \u003cli\u003e2020 Chevrolet Colorado 2.5L L4 Base, WT, LT\u003c\/li\u003e\n  \u003cli\u003e2021 Chevrolet Colorado 2.5L L4 WT, LT\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chevrolet Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the continuous duty cycles and thermal loads required of a working mid-size pickup, this ignition system ensures consistent combustion stability under payload and towing conditions without premature spark degradation.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50449174528248,"sku":"DS-EBE0P2LJD","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-chevrolet-colorado-2015-2021-2-5l-1.jpg?v=1788668789","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-chevrolet-colorado-2015-2021-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
