This thermal fatigue, combined with natural electrode erosion on aging spark plugs, increases resistance across the secondary ignition circuit. The result is weakened spark output, hesitation under load, erratic idle speed, and diagnostic trouble codes such as P0300 through P0306.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive service kit includes six reinforced coil-on-plug assemblies engineered with high-conductivity copper primary and secondary windings, heavy-duty thermoplastic housings, and OEM-spec direct-fit blade terminals. Paired with six fine-wire iridium spark plugs engineered for superior thermal resistance and gap stability, this package provides consistent spark energy, robust flame kernel propagation, and dependable high-load combustion efficiency.\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 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;\"\u003e3.6L LGZ V6 \/ GMT 31XX\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;\"\u003e308 hp \/ 275 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;\"\u003eUF830, 12666339, 12688894, C962, C2035, 5C2094, GN10889\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2017 Chevrolet Colorado 3.6L V6 (LT, WT, Z71, ZR2)\u003c\/li\u003e\n  \u003cli\u003e2018 Chevrolet Colorado 3.6L V6 (LT, WT, Z71, ZR2)\u003c\/li\u003e\n  \u003cli\u003e2019 Chevrolet Colorado 3.6L V6 (LT, WT, Z71, ZR2)\u003c\/li\u003e\n  \u003cli\u003e2020 Chevrolet Colorado 3.6L V6 (LT, WT, Z71, ZR2)\u003c\/li\u003e\n  \u003cli\u003e2021 Chevrolet Colorado 3.6L V6 (LT, WT, Z71, ZR2)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chevrolet Colorado Durability Standard\u003c\/h3\u003e\n\u003cp\u003eDesigned to withstand the harsh thermal and vibrational demands of heavy payload hauling and sustained towing, this ignition kit maintains consistent spark delivery under peak cylinder pressures without spark blowout or thermal degradation.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50449184162040,"sku":"DS-EJTRA6MC7","price":129.95,"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-2017-2021-3-6l-1.jpg?v=1788669096","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-chevrolet-colorado-2017-2021-3-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
