Over thousands of heat cycles, factory internal windings degrade and lower boot insulation weakens, causing high electrical resistance, current leakage, and inconsistent spark arc. Coupled with electrode wear on aging plugs, this deterioration leads to hesitation under load, decreased fuel economy, and P0300-P0304 misfire diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition tune-up kit features four high-grade coil-on-plug assemblies engineered with premium copper windings and high-dielectric epoxy potting to resist thermal fatigue and prevent voltage flashover. Paired with four fine-wire iridium spark plugs, this setup lowers required ignition voltage while maintaining superior spark kernel growth. The corrosion-resistant blade terminals and OEM-spec direct-fit connectors ensure drop-in installation with stable electrical conductivity under hard acceleration.\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;\"\u003e2009-2012 Nissan Sentra\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 2.5L I4 \/ 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;\"\u003e177-200 hp \/ 172-180 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;\"\u003eUF549, UF-549, UF509\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2009 Nissan Sentra SE-R \/ SE-R Spec V (2.5L L4 Gas)\u003c\/li\u003e\n  \u003cli\u003e2010 Nissan Sentra SE-R \/ SE-R Spec V (2.5L L4 Gas)\u003c\/li\u003e\n  \u003cli\u003e2011 Nissan Sentra SE-R \/ SE-R Spec V (2.5L L4 Gas)\u003c\/li\u003e\n  \u003cli\u003e2012 Nissan Sentra SE-R \/ SE-R Spec V (2.5L L4 Gas)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Nissan Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet the rapid combustion demands of the QR25DE platform, this kit delivers consistent high-voltage discharge without ECM communication errors or check engine lights, restoring sharp throttle response to your Sentra.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50452875772152,"sku":"DS-E8TPSKRMI","price":78.95,"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-2009-2012-2-5l-1.jpg?v=1788725960","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-nissan-sentra-2009-2012-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
