Over extended mileage, thermal cycling degrades the internal potting epoxy, inducing micro-cracks and dielectric breakdown in the primary and secondary copper windings. Concurrently, factory spark plugs experience electrode erosion that widens the gap, increasing the secondary voltage demand and stressing tired coils until hesitation, catalyst-damaging unburnt fuel wash, and P0300-P0304 diagnostic trouble codes occur.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement ignition package features four heavy-duty ignition coils paired with four laser-welded iridium spark plugs. The coil assemblies are engineered with high-purity internal copper windings and reinforced dielectric boots to resist thermal breakdown and current leakage. Matched with fine-wire iridium center electrodes, this kit reduces the required ionization voltage, promotes immediate flame kernel expansion, and ensures reliable combustion stability from cold start to high-RPM operation.\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;\"\u003e2003-2005 Mazda 6\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;\"\u003e2.3L L3-VE (MZR) \/ GG\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;\"\u003e160 hp \/ 155 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;\"\u003eDG541, DG507, FD505, UF621\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2003 Mazda 6 (2.3L L4 Gas)\u003c\/li\u003e\n  \u003cli\u003e2004 Mazda 6 (2.3L L4 Gas)\u003c\/li\u003e\n  \u003cli\u003e2005 Mazda 6 (2.3L L4 Gas)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Mazda Reliability Caliber\u003c\/h3\u003e\n\u003cp\u003eDesigned specifically to maintain the responsive rev characteristics of the MZR platform, this ignition service kit delivers consistent spark energy, optimized fuel economy, and dependable everyday drivability without trigger codes or electrical interference.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50452570505464,"sku":"DS-EKD5V0P5D","price":67.95,"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-mazda-6-2003-2005-2-3l-1.jpg?v=1788722392","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-mazda-6-2003-2005-2-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
