Over time, internal epoxy insulation hardens and develops micro-fractures, while primary and secondary copper windings increase in internal resistance. Concurrently, standard electrode erosion on aging plugs expands the gap clearance, driving up required firing voltage and precipitating spark blow-out, severe cold-start hesitation, and intermittent P0300-P0304 fault codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit restores high-voltage energy transfer via four reinforced coil-on-plug units wound with high-conductivity oxygen-free copper and insulated with high-dielectric epoxy resin. Matched with four fine-wire iridium spark plugs, the assembly withstands high thermal loads and resists arc-over. The reduced electrode surface area requires lower breakdown voltage, ensuring a stable, localized flame kernel under all throttle transitions.\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;\"\u003eMR20DE 2.0L \/ 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;\"\u003e140 hp \/ 147 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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2009-2012 Nissan Sentra Base (2.0L L4 MR20DE)\u003c\/li\u003e\n  \u003cli\u003e2009-2012 Nissan Sentra S (2.0L L4 MR20DE)\u003c\/li\u003e\n  \u003cli\u003e2009-2012 Nissan Sentra SL (2.0L L4 MR20DE)\u003c\/li\u003e\n  \u003cli\u003e2009-2012 Nissan Sentra SR (2.0L L4 MR20DE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Nissan Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM operational tolerances, this kit restores clean throttle response, factory fuel economy, and crisp combustion stability across the entire RPM band without triggering false diagnostic trouble codes.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50452225687800,"sku":"DS-EMU80RWKA","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-2009-2012-2-0l-1.jpg?v=1788721265","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-nissan-sentra-2009-2012-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
