Located deep within the engine bay, the VQ40DE ignition system experiences continuous extreme heat soak cycles. Over time, the internal epoxy potting within the OEM coils degrades, leading to micro-cracks in the housing. This breakdown compromises secondary voltage output, causing intermittent misfires, increased emissions, and sluggish throttle response. Additionally, factory standard spark plugs gradually suffer from electrode erosion, widening the spark gap and forcing the degrading ignition coils to work even harder to bridge the gap, which ultimately accelerates total ignition failure.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis comprehensive six-pack of upgraded ignition coils and high-performance iridium spark plugs provides a permanent mechanical fix for the VQ40DE. The replacement coils are manufactured with high-dielectric epoxy and heavy-duty copper windings to maximize energy transfer and eliminate voltage leaks under heavy operating loads. The reinforced polymer housings resist the thermal shock and mechanical vibration common in rigorous off-road environments. Paired with the ultra-fine wire iridium center electrodes of the included spark plugs, this kit guarantees a concentrated, consistent spark. The iridium material drastically reduces the required firing voltage, relieving stress on the coils while ensuring complete fuel vaporization for restored power and optimal efficiency.\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;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2005-2015 Nissan Xterra\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eVQ40DE \/ N50\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e261 hp \/ 281 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e224338J11C, 224488J100, 224488J110, 224488J111, 224488J115, 224488J11C, C1406-6\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2005-2015 Nissan Xterra PRO-4X (4.0L V6)\u003c\/li\u003e\n    \u003cli\u003e2005-2015 Nissan Xterra S (4.0L V6)\u003c\/li\u003e\n    \u003cli\u003e2005-2015 Nissan Xterra X (4.0L V6)\u003c\/li\u003e\n    \u003cli\u003e2005-2015 Nissan Xterra SE (4.0L V6)\u003c\/li\u003e\n    \u003cli\u003e2005-2015 Nissan Xterra Off-Road (4.0L V6)\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Nissan Durability Standard\u003c\/h3\u003e\n  \u003cp\u003eDesigned for the rigorous demands of truck and SUV applications, this ignition kit ensures your Xterra maintains peak reliability whether you are towing a trailer or navigating challenging off-road trails.
