Over time, thermal expansion degrades the internal epoxy potting, causing micro-fracturing across the secondary copper windings. This leads to dielectric breakdown and high-voltage flashover under load. Simultaneously, factory spark plugs suffer from center-electrode erosion and gap enlargement, drastically increasing the required secondary firing voltage. The result is unburnt fuel wash, intermittent \u003cstrong\u003eP0300\u003c\/strong\u003e to \u003cstrong\u003eP0304\u003c\/strong\u003e diagnostic trouble codes, sluggish tip-in response, and accelerated catalytic converter wear.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition kit features four heavy-duty pencil ignition coils and four fine-wire iridium spark plugs precision-engineered for the \u003cstrong\u003eQR25DE\u003c\/strong\u003e platform. The coils utilize high-grade magnetic steel cores, electrolytic copper windings, and advanced thermoplastic housings to resist thermal fatigue and prevent voltage leakage. Matched with laser-welded iridium electrode spark plugs featuring trivalent metal plating to prevent seizing and corrosion, this system optimizes flame kernel propagation, reduces required ignition voltage, and delivers consistent spark delivery across the entire rev range.\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;\"\u003e2014-2017 Nissan X-Trail\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\u003eQR25DE\u003c\/strong\u003e \/ \u003cstrong\u003eT32\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;\"\u003e170 hp \/ 175 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\u003e22448EA000\u003c\/strong\u003e, \u003cstrong\u003eUF509\u003c\/strong\u003e, \u003cstrong\u003e3340082Z20\u003c\/strong\u003e, MPN: \u003cstrong\u003eKIN133718TOP\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2014 Nissan X-Trail (T32) 2.5L 4-Cylinder QR25DE\u003c\/li\u003e\n  \u003cli\u003e2015 Nissan X-Trail (T32) 2.5L 4-Cylinder QR25DE\u003c\/li\u003e\n  \u003cli\u003e2016 Nissan X-Trail (T32) 2.5L 4-Cylinder QR25DE\u003c\/li\u003e\n  \u003cli\u003e2017 Nissan X-Trail (T32) 2.5L 4-Cylinder QR25DE\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the T32 X-Trail?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2014-2017 Nissan X-Trail equipped with the \u003cstrong\u003eQR25DE\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the iridium spark plugs pre-gapped for direct installation?\u003c\/strong\u003e\u003cbr\u003e Yes, all included spark plugs arrive pre-gapped to factory factory clearance specifications for immediate bolt-on installation without manual adjustment.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan Durability Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to withstand daily commuter stress and rugged weekend utility, this ignition kit restores the dependable power delivery and fuel economy that Nissan cross-utility vehicle owners depend on.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50593983463672,"sku":"DS-EDRI49IJM","price":89.95,"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-x-trail-2014-2017-2-5l-1.jpg?v=1790055016","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-nissan-x-trail-2014-2017-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
