Over time, OEM epoxy insulation deteriorates, resulting in internal copper breakdown, micro-arcing, and secondary voltage drop. Combined with standard worn electrode gaps on aged plugs, this degradation produces incomplete burn cycles, hesitation under load, poor fuel economy, and random P0300 misfire fault codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit features heavy-duty coil-on-plug units engineered with high-grade internal copper windings and thermoplastic housings resistant to dielectric breakdown. Paired with fine-wire iridium spark plugs, the system reduces the voltage required to jump the spark gap. The corrosion-resistant iridium center electrode maintains precise gap clearance under high cylinder pressures, delivering consistent spark propagation and crisp throttle response.\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;\"\u003e2007-2012 Nissan Versa 1.8L\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 \/ C11\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\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\u003e2007-2012 Nissan Versa Base (1.8L I4 MR18DE)\u003c\/li\u003e\n  \u003cli\u003e2007-2012 Nissan Versa S (1.8L I4 MR18DE)\u003c\/li\u003e\n  \u003cli\u003e2007-2012 Nissan Versa SL (1.8L I4 MR18DE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Nissan Precision Calibration\u003c\/h3\u003e\n\u003cp\u003eEngineered to exact OEM resistance tolerances, this kit installs seamlessly into factory wiring harnesses without causing electronic interference or trigger codes, delivering factory-grade driveability across all operational RPM ranges.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50452221591800,"sku":"DS-E3G3DF5LC","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-versa-2007-2012-1-8l-1.jpg?v=1788721117","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-nissan-versa-2007-2012-1-8l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
