Over continuous heat cycles, secondary winding resistance climbs, causing dielectric breakdown, erratic spark timing, high-load spark blowout, and severe P0300-P0304 misfire codes that compromise fuel efficiency and throttle response.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service kit pairs four heavy-duty coil-on-plug assemblies featuring high-grade internal copper windings and high-dielectric epoxy with four fine-wire iridium spark plugs. The copper windings provide consistent high-voltage discharge under boost and compression, while the fine-wire iridium electrodes resist thermal erosion, reduce required ionization voltage, and maintain precise gap tolerances across high-RPM operation.\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;\"\u003e2002-2008 Nissan Sentra 2.5L\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;\"\u003eQR25DE \/ B15, B16\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;\"\u003e175-200 hp \/ 180 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;\"\u003eUF350, UF-350\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2002-2006 Nissan Sentra SE-R \/ SE-R Spec V 2.5L L4 (B15)\u003c\/li\u003e\n  \u003cli\u003e2003-2006 Nissan Sentra Limited Edition 2.5L L4 (B15)\u003c\/li\u003e\n  \u003cli\u003e2007-2008 Nissan Sentra SE-R \/ SE-R Spec V 2.5L L4 (B16)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Nissan Performance Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to withstand the demanding high-revving nature of tuned naturally aspirated JDM platforms, this ignition kit delivers crisp throttle modulation, clean combustion cycles, and reliable cold-start operation under heavy operational duty.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50452010631416,"sku":"DS-EDXP9U0VR","price":73.95,"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-sentra-2002-2008-2-5l-1.jpg?v=1788716991","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-nissan-sentra-2002-2008-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
