Simultaneously, factory spark plug ground electrodes erode over extended service intervals, increasing the required firing voltage. This elevated resistance overtaxes worn coils, leading to high-load spark blowout, hesitation during towing, unburned hydrocarbon buildup, and diagnostic trouble codes such as P0300 through P0308.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service replacement kit restores full spark delivery by pairing eight heavy-duty ignition coils with precision NGK Platinum spark plugs. Designed to meet or exceed \u003cstrong\u003eUF414\u003c\/strong\u003e OE specifications, the coils feature high-conductivity copper windings and heat-resistant silicone boots to resist dielectric puncture and heat soak. The matched NGK Platinum plugs maintain stable gap dimensions under severe combustion pressures, promoting uniform flame kernel expansion, crisp throttle response, and consistent ignition saturation through the entire rev band.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e8x Replacement Ignition Coils (Replaces UF414)\u003c\/li\u003e\n  \u003cli\u003e8x 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;\"\u003e2017-2018 GMC Sierra\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;\"\u003e\n\u003cstrong\u003eL96\u003c\/strong\u003e Vortec 6.0L V8 \/ \u003cstrong\u003eK2XX\u003c\/strong\u003e\n\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;\"\u003e360 hp \/ 380 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;\"\u003e\u003cstrong\u003eUF414\u003c\/strong\u003e\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 GMC Sierra 2500 HD 6.0L V8\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 K2XX Sierra?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2017-2018 GMC Sierra equipped with the \u003cstrong\u003eL96\u003c\/strong\u003e 6.0L engine. \u003cstrong\u003eThis kit is not compatible with 5.3L or 6.2L EcoTec3 engines or applications with alternative coil harness connector configurations.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eAre spark plug wires included with this ignition package?\u003c\/h4\u003e\n\u003cp\u003eSpark plug wires are not included with this kit and must be inspected and reused or replaced separately.\u003c\/p\u003e\n\n\u003ch3\u003eThe GMC Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for high-demand work trucks, this ignition package provides the dependable spark discharge required to maintain rated payload capacities and steep-grade hauling power without misfires.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67562627465464,"sku":"DS-ETRQCMW23","price":261.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-gmc-sierra-2017-2018-6-0l-1.jpg?v=1790987321","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-spark-plugs-for-gmc-sierra-2017-2018-6-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
