Over time, the factory ignition coils suffer from dielectric breakdown due to intense thermal cycling within the engine bay and proximity to the exhaust manifold. This continuous heat exposure degrades the internal epoxy potting and primary windings, leading to voltage leaks, sluggish throttle response, rough idle, and inevitable cylinder misfires under load. Furthermore, aging standard spark plugs rapidly erode their gap, forcing the weakened coils to work harder to jump the spark, ultimately causing premature ignition failure and decreased fuel economy.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition overhaul kit addresses the inherent weaknesses of the OEM setup by utilizing upgraded materials and precise manufacturing. The replacement ignition coils feature heavy-duty copper wire internals and superior dielectric epoxy to resist heat soak and voltage blow-out under extreme combustion chamber pressures. Paired with the included Iridium spark plugs—which offer a much higher melting point and finer center electrode than standard copper or platinum plugs—this kit delivers a highly concentrated, consistent spark. This translates to an estimated 15% increase in combustion energy transfer, completely eliminating high-RPM misfires, stabilizing the idle, and maximizing the efficiency of your CX-7's powerplant.\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 Mazda CX-7\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;\"\u003eL3-VDT (2.3L) \u0026amp; L5-VE (2.5L) \/ ER Chassis\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;\"\u003e161-244 hp \/ 161-258 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, E1040, L3K9-18-100-B, L3G2-18-100-A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2007 Mazda CX-7 2.3L Turbo\u003c\/li\u003e\n  \u003cli\u003e2008 Mazda CX-7 2.3L Turbo\u003c\/li\u003e\n  \u003cli\u003e2009 Mazda CX-7 2.3L Turbo\u003c\/li\u003e\n  \u003cli\u003e2010 Mazda CX-7 2.3L Turbo\u003c\/li\u003e\n  \u003cli\u003e2010 Mazda CX-7 2.5L Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e2011 Mazda CX-7 2.3L Turbo\u003c\/li\u003e\n  \u003cli\u003e2011 Mazda CX-7 2.5L Naturally Aspirated\u003c\/li\u003e\n  \u003cli\u003e2012 Mazda CX-7 2.3L Turbo\u003c\/li\u003e\n  \u003cli\u003e2012 Mazda CX-7 2.5L Naturally Aspirated\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Mazda Calibration Standard\u003c\/h3\u003e\n\u003cp\u003eWhen dealing with precision JDM-derived platforms like the CX-7, maintaining optimal spark energy is critical for both power delivery and long-term reliability.
