Positioned directly above the 2.0L LF-VE engine, the OEM coils endure constant heat cycling, which breaks down the internal epoxy potting and copper winding insulation. As this insulation degrades, resistance increases, leading to a weaker spark, random misfires under load, and poor idle quality. Coupled with standard copper or worn platinum spark plugs, this weakened voltage output fails to fully ignite the air-fuel mixture, resulting in increased carbon buildup on the valves and a noticeable drop in throttle response and fuel economy.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis upgraded ignition kit resolves NC Miata spark blowout and misfire issues by utilizing high-quality copper wire internals with advanced thermal-resistant epoxy potting. The upgraded coil design maintains stable voltage output even under extreme engine bay temperatures, ensuring consistent spark delivery to the combustion chamber. Paired with the included Iridium spark plugs, which feature an ultra-fine center electrode, the system requires less voltage to generate a spark while delivering a more concentrated ignition point. This results in up to a 15% increase in ignition energy transfer, promoting complete combustion, sharper throttle response, and reliable performance throughout the entire RPM range. These coils meet or exceed OE+ durability standards, providing a direct plug-and-play solution.\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;\"\u003e2006-2015 Mazda MX-5 Miata\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;\"\u003eLF-VE 2.0L \/ NC\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;\"\u003e167 hp \/ 140 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;\"\u003eUF540, 5C1740, 178-8350, 178-8527, E1040, L3G2-18-100-B-9U, L3K9-18-100-A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2006 Mazda MX-5 Miata 2.0L\u003c\/li\u003e\n  \u003cli\u003e2007 Mazda MX-5 Miata 2.0L\u003c\/li\u003e\n  \u003cli\u003e2008 Mazda MX-5 Miata 2.0L\u003c\/li\u003e\n  \u003cli\u003e2009 Mazda MX-5 Miata 2.0L\u003c\/li\u003e\n  \u003cli\u003e2010 Mazda MX-5 Miata 2.0L\u003c\/li\u003e\n  \u003cli\u003e2011 Mazda MX-5 Miata 2.0L\u003c\/li\u003e\n  \u003cli\u003e2012 Mazda MX-5 Miata 2.0L\u003c\/li\u003e\n  \u003cli\u003e2013 Mazda MX-5 Miata 2.0L\u003c\/li\u003e\n  \u003cli\u003e2014 Mazda MX-5 Miata 2.0L\u003c\/li\u003e\n  \u003cli\u003e2015 Mazda MX-5 Miata 2.0L\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Mazda Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for the lightweight, high-revving nature of JDM sports cars, this ignition overhaul restores the crisp, responsive power delivery expected from the NC Miata, ensuring reliable performance on both the street and the autocross track.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50062646804728,"sku":"DS-EZJP3J11X","price":99.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-iridium-spark-plugs-for-mazda-mx-5-miata-2006-2015-2-0l-1.jpg?v=1785171557","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-iridium-spark-plugs-for-mazda-mx-5-miata-2006-2015-2-0l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
