Over time, heat soak degrades the internal epoxy resin and insulation around the primary and secondary copper windings, causing micro-arcing and internal resistance breakdown. Concurrently, standard OEM spark plugs suffer from electrode erosion and gap enlargement, requiring higher breakdown voltage that overburdens aging coil packs and triggers P0300-P0304 diagnostic trouble codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete tune-up kit pairs heavy-duty coil-on-plug assemblies with fine-wire iridium spark plugs. The ignition coils feature premium-grade internal copper windings and high-dielectric silicone boots that resist dielectric breakdown under sustained operating temperatures. Paired with laser-welded iridium electrode spark plugs, this setup lowers required firing voltage, provides a consistent spark kernel, prevents blow-out under load, and optimizes flame front propagation across the combustion chamber.\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;\"\u003e2009-2014 Nissan Cube\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;\"\u003eMR18DE \/ Z12\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;\"\u003e122 hp \/ 127 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 Nissan Cube 1.8L L4 (Base, S, SL, Krom)\u003c\/li\u003e\n  \u003cli\u003e2010 Nissan Cube 1.8L L4 (Base, S, SL, Krom)\u003c\/li\u003e\n  \u003cli\u003e2011 Nissan Cube 1.8L L4 (Base, S, SL, Krom)\u003c\/li\u003e\n  \u003cli\u003e2012 Nissan Cube 1.8L L4 (Base, S, SL)\u003c\/li\u003e\n  \u003cli\u003e2013 Nissan Cube 1.8L L4 (Base, S, SL)\u003c\/li\u003e\n  \u003cli\u003e2014 Nissan Cube 1.8L L4 (Base, S, SL)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Nissan JDM Efficiency Caliber\u003c\/h3\u003e\n\u003cp\u003eEngineered to deliver crisp throttle response and clean combustion, this ignition service package ensures dependable daily drivability, smooth power delivery, and optimal fuel economy for your compact cruiser.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50452223492344,"sku":"DS-E6QYCROYA","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-cube-2009-2014-1-8l-1.jpg?v=1788721176","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-nissan-cube-2009-2014-1-8l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
