Over time, OEM coil windings degrade from cyclic heat soak, leading to internal dielectric insulation failure, high-rpm misfires, and spark blowout. Concurrently, factory spark plugs suffer electrode erosion, widening the plug gap and forcing the ignition coils to draw excessive primary current, which triggers hesitation and diagnostic trouble codes under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-fit ignition service kit provides six coil-on-plug assemblies manufactured with high-conductivity internal copper windings and heavy-duty thermoplastic housings to resist dielectric breakdown. Paired with six fine-wire iridium spark plugs, the assembly delivers a focused spark kernel requiring lower ionization voltage. This combination maintains consistent flame-front propagation, smooths idle harmonics, and prevents unburnt fuel fouling under aggressive throttle input.\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;\"\u003e2019-2020 Chevrolet Blazer 3.6L V6\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 LGX V6 \/ C1XX Platform\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 \/ 270 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, UF-830, C-962, C2035, 5C2094, GN10889, 12666339\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2019 Chevrolet Blazer (3.6L V6 - RS, Premier, Cloth, Leather)\u003c\/li\u003e\n  \u003cli\u003e2020 Chevrolet Blazer (3.6L V6 - RS, Premier, 2LT, 3LT)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chevrolet Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet rigorous crossover utility demands, this complete ignition refresh preserves cold-weather starting reliability, stabilizes towing power delivery, and protects catalytic converters from raw hydrocarbon contamination.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50448509370616,"sku":"DS-E4652JN7I","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-blazer-2019-2020-3-6l-1.jpg?v=1788648437","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-chevrolet-blazer-2019-2020-3-6l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
