Over sustained operation, the factory coil-on-plug pencil coils suffer dielectric breakdown in the internal epoxy insulation and secondary windings due to severe thermal cycling within the compact \u003cstrong\u003eRZ34\u003c\/strong\u003e engine bay. Simultaneously, factory spark plug ground straps experience rapid electrical erosion under high cylinder pressures, widening the spark gap. This gap expansion strains aging ignition coils, triggering high-rpm spark blowout, intermittent misfires, ECU timing retardation, and lost throttle response during boost spool.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition refresh kit pairs six high-output pencil coils with precision-gapped fine-wire iridium spark plugs designed specifically for forced-induction thermal loads. Each coil housing utilizes reinforced thermal-resistant PBT polymer and high-grade copper windings to resist insulation breakdown and maintain stable secondary voltage output under continuous load. The included iridium spark plugs feature a laser-welded fine-wire center electrode and platinum-tipped ground electrode, lowering required firing voltage while resisting electrode rounding and carbon fouling. This direct-replacement package restores factory dwell response, directly referencing OE interchange numbers \u003cstrong\u003e224485NA0A\u003c\/strong\u003e, \u003cstrong\u003eUF819\u003c\/strong\u003e, and \u003cstrong\u003e224485CA0A\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;\"\u003e2023-2025 Nissan Z\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;\"\u003eVR30DDTT \/ RZ34\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;\"\u003e400 hp \/ 350 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;\"\u003e224485NA0A, UF819, 224485CA0A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2023-2025 Nissan Z Sport 3.0L V6 Twin-Turbo (VR30DDTT)\u003c\/li\u003e\n  \u003cli\u003e2023-2025 Nissan Z Performance 3.0L V6 Twin-Turbo (VR30DDTT)\u003c\/li\u003e\n  \u003cli\u003e2024-2025 Nissan Z NISMO 3.0L V6 Twin-Turbo (VR30DDTT)\u003c\/li\u003e\n  \u003cli\u003e2023 Nissan Z Proto Spec 3.0L V6 Twin-Turbo (VR30DDTT)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the RZ34 Z?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2023-2025 Nissan Z equipped with the VR30DDTT engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo these spark plugs require pre-gapping prior to installation?\u003c\/strong\u003e\u003cbr\u003e The iridium plugs come factory pre-gapped for OEM boost levels, though inspecting gap clearance with a feeler gauge prior to installation is standard practice.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to sustain the high-revving power delivery and forced-induction demands of Nissan's sports coupe heritage without spark blowout or voltage breakdown.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50603775787256,"sku":"DS-EOKIZTI9K","price":113.95,"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-nissan-z-2023-2025-3-0l-1.jpg?v=1790088364","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-nissan-z-2023-2025-3-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
