The original \u003cstrong\u003eUF413\u003c\/strong\u003e and \u003cstrong\u003e12611424\u003c\/strong\u003e round-style coils suffer internal epoxy breakdown and primary winding degradation from extreme underhood heat soak. Simultaneously, factory spark plugs suffer center electrode erosion and enlarged gaps past 0.040 inches, drastically elevating secondary breakdown voltage requirements. This voltage stress induces high-rpm spark blowout, intermittent hesitation under heavy payload or towing loads, unburnt hydrocarbon build-up, and recurring P0300 to P0308 diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service kit resolves secondary ignition collapse by matching 8 high-dielectric replacement coil packs with 8 wear-resistant \u003cstrong\u003eNGK Platinum\u003c\/strong\u003e spark plugs. Built to direct-fit \u003cstrong\u003eD510C\u003c\/strong\u003e specifications, each coil utilizes high-temperature epoxy potting and heavy-gauge copper windings to resist insulation breakdown and maintain primary circuit saturation. Paired with NGK's fine-wire platinum center electrodes, the system lowers required firing voltages, suppresses quench effects, and maintains stable flame-front propagation across the full operating range of the \u003cstrong\u003eL96\u003c\/strong\u003e Vortec engine.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e8 Energy Ignition Coils\u003c\/li\u003e\n  \u003cli\u003e8 NGK Platinum Spark Plugs\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;\"\u003e2017-2020 Chevrolet Express\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;\"\u003e6.0L Vortec L96 (Gen IV LS) \/ GMT610\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;\"\u003e341 hp \/ 373 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;\"\u003eUF413, 3186, 178-8411, GN10165, IC533, 8265, 82653, 48713, U5132, C-721, D510C, 12570616, 12611424, D513A, 140043, 140043-8, 140043K, 140043K-8, 2IC422, 50227, 36-1192, 5115, 2505-311071, E893, C1351, C1511, C1511-8, 2-50069, C1511DLGKIT, 8125706160, 8126114240, 5C1154, 5C1554, IC533SB, UF413T, 673-7002, 52-1712, 52-1819, C1511SPEC, 2-50227, EBC1789, 26A1042, 098622A210, IGC0150, GM1316053, SKIC048, CUF413, C1511VC, 920-1061, 2IGC0303\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\u003e2017-2018 Chevrolet Express 2500 6.0L\u003c\/li\u003e\n  \u003cli\u003e2017-2020 Chevrolet Express 3500 6.0L\u003c\/li\u003e\n  \u003cli\u003e2017 Chevrolet Express 4500 6.0L\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 GMT610 Express?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2017-2020 Chevrolet Express equipped with the 6.0L \u003cstrong\u003eL96\u003c\/strong\u003e engine; confirm your existing setup uses the round coil body matching \u003cstrong\u003eUF413\u003c\/strong\u003e \/ \u003cstrong\u003eD510C\u003c\/strong\u003e before ordering, as it does not fit other displacements or square coil configurations.\u003c\/p\u003e\n\n\u003ch4\u003eAre spark plug wires included with this service kit?\u003c\/h4\u003e\n\u003cp\u003eSpark plug wires are not included; this kit contains only the 8 replacement ignition coils and 8 NGK platinum plugs.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Commercial Standard\u003c\/h3\u003e\n\u003cp\u003eWhen operating a dedicated commercial fleet or heavy towing vehicle, secondary ignition integrity is essential.
