Over heat cycles, the original coil pack epoxy insulation degrades, creating micro-fractures in the casing. This leads to internal dielectric breakdown, secondary winding voltage leakage, and incomplete combustion in the \u003cstrong\u003eVK45DE\u003c\/strong\u003e engine. Compounding this, aged spark plugs with eroded ground electrodes demand higher firing voltage from stressed coils, triggering intermittent misfires (P0300–P0308 codes), hesitant acceleration, and unburnt hydrocarbon buildup in the catalytic converters.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive service pack replaces all eight coil-on-plug units and spark plugs simultaneously to re-establish balanced impedance across all banks. Manufactured with high-conductivity copper primary and secondary windings, each coil delivers consistent high-voltage output across high-RPM operation. Reinforced silicone boots prevent spark flashover to the aluminum cylinder head, while matching precision-gapped spark plugs offer optimal heat dissipation and anti-fouling durability under continuous thermal load.\u003c\/p\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;\"\u003e2002-2006 Infiniti Q45\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\u003eVK45DE\u003c\/strong\u003e \/ \u003cstrong\u003eF50\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;\"\u003e340 hp \/ 333 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\n\u003cstrong\u003eUF482\u003c\/strong\u003e, \u003cstrong\u003e5C1407\u003c\/strong\u003e, \u003cstrong\u003eE1068\u003c\/strong\u003e, \u003cstrong\u003eE962\u003c\/strong\u003e, \u003cstrong\u003e52-1757\u003c\/strong\u003e, \u003cstrong\u003eIC562\u003c\/strong\u003e, \u003cstrong\u003e22058\u003c\/strong\u003e, \u003cstrong\u003e33ICPA741\u003c\/strong\u003e\n\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\u003e2002-2006 Infiniti Q45 4.5L V8 (VK45DE Engine)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the F50 Q45?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2002-2006 Infiniti Q45 equipped with the \u003cstrong\u003eVK45DE\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eShould spark plugs and coils always be replaced as a complete set?\u003c\/h4\u003e\n\u003cp\u003eReplacing coils and plugs together ensures balanced secondary resistance across all cylinders, eliminating uneven idle and preventing old plugs from prematurely overworking new coil windings.\u003c\/p\u003e\n\n\u003ch3\u003eThe Infiniti Benchmark\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet the tight tolerances of Nissan's flagship 32-valve V8, this ignition package delivers precise flame kernel propagation to maintain the smooth, responsive power delivery expected from an executive performance sedan.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67518832836856,"sku":"DS-EIL757CAX","price":209.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-infiniti-q45-2002-2006-4-5l-1.jpg?v=1790370787","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-spark-plugs-for-infiniti-q45-2002-2006-4-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
