Over time, micro-cracks form in the epoxy encapsulation of aged OEM coils, while plug gap erosion steadily increases resistance. On high-mileage \u003cstrong\u003e2UZ-FE\u003c\/strong\u003e engines, this breakdown triggers secondary voltage leakage, intermittent misfires under load (DTC P0300–P0308), diminished fuel economy, and cataloged catalytic converter degradation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive service kit pairs heavy-duty coil packs featuring high-dielectric epoxy potting and premium magnetic core laminations with matched platinum spark plugs. The coils resist thermal breakdown and sustain required discharge energy across extreme duty cycles, while the platinum plug electrodes maintain precise gap tolerances and resist fouling. Designed to plug directly into the factory wiring harness without adaptation, this package restores crisp throttle response and clean flame propagation.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e8 Energy Ignition Coils (Replacement for \u003cstrong\u003eUF230\u003c\/strong\u003e)\u003c\/li\u003e\n  \u003cli\u003e8 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;\"\u003e2000-2004 Toyota Tundra\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\u003e2UZ-FE\u003c\/strong\u003e \/ \u003cstrong\u003eXK30\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;\"\u003e245 hp \/ 315 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\u003eUF230\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\u003e2000-2004 Toyota Tundra 4.7L 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 XK30 Tundra?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 2000-2004 Toyota Tundra equipped with the \u003cstrong\u003e2UZ-FE\u003c\/strong\u003e 4.7L V8 engine; it does not fit 3.4L V6 models.\u003c\/p\u003e\n\n\u003ch4\u003eAre spark plug wires required for installation?\u003c\/h4\u003e\n\u003cp\u003eNo, the \u003cstrong\u003e2UZ-FE\u003c\/strong\u003e utilizes an independent coil-on-plug setup where each coil connects directly to the plug terminal, eliminating high-tension ignition wires.\u003c\/p\u003e\n\n\u003ch3\u003eThe Toyota Truck Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to endure severe towing demands and rough terrain, this replacement ignition package maintains dependable combustion stability and payload capacity under sustained thermal stress.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67562508255480,"sku":"DS-EKXZ9Q71W","price":166.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-toyota-tundra-2000-2004-4-7l-1.jpg?v=1790982834","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-spark-plugs-for-toyota-tundra-2000-2004-4-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
