Over miles of service, high underhood heat breaks down the internal primary and secondary copper windings, while dielectric epoxy degrades and micro-cracks. This insulation failure leads to secondary voltage leakage, internal arcing, and intermittent P0300 through P0304 misfire DTCs under load. Simultaneously, standard nickel-core or fatigued OEM spark plugs suffer from eroded center electrodes and widened gaps, which severely spikes coil dwell times and burns out secondary coil drivers prematurely.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit pairs heavy-duty coil packs with high-conductivity iridium spark plugs designed specifically for the \u003cstrong\u003eGMT355\u003c\/strong\u003e platform. The ignition coils feature premium copper windings insulated with vacuum-poured dielectric epoxy to resist heat soak, vibration, and internal carbon tracking. Each plug incorporates a laser-welded, fine-wire 0.6mm iridium center electrode and platinum ground pad, requiring lower secondary ionization voltage while producing a faster, more concentrated flame kernel. This setup prevents spark blowout, minimizes parasitic electrical loads on the PCM, and directly replaces OEM part numbers \u003cstrong\u003e12596547\u003c\/strong\u003e, \u003cstrong\u003e12612369\u003c\/strong\u003e, and \u003cstrong\u003eUF497\u003c\/strong\u003e.\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; margin-bottom: 20px;\"\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;\"\u003e2007-2012 GMC Canyon\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;\"\u003e2.9L Vortec LLV I4 \/ GMT355\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;\"\u003e185 hp \/ 190 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;\"\u003e12596547, 12612369, UF497\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2007-2012 GMC Canyon WT (2.9L I4 LLV)\u003c\/li\u003e\n  \u003cli\u003e2007-2012 GMC Canyon SLE (2.9L I4 LLV)\u003c\/li\u003e\n  \u003cli\u003e2007-2012 GMC Canyon SL (2.9L I4 LLV)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the GMT355 Canyon?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2007-2012 GMC Canyon equipped with the 2.9L LLV engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo these spark plugs require manual gapping prior to installation?\u003c\/strong\u003e\u003cbr\u003e No, iridium fine-wire plugs are pre-gapped to factory specifications; manual gapping can fracture the brittle iridium center electrode.\u003c\/p\u003e\n\n\u003ch3\u003eThe GMC Truck Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle sustained payload hauling and daily job-site duty, this ignition package delivers the uncompromised combustion stability and thermal resistance essential for dependable fleet and midsize truck performance.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50594030977272,"sku":"DS-EXNVB6M2Z","price":85.95,"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-gmc-canyon-2007-2012-2-9l-1.jpg?v=1790056189","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-gmc-canyon-2007-2012-2-9l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
