As the factory epoxy resin and copper windings undergo continuous heat soak, internal resistance increases, causing weak spark delivery, intermittent cylinder misfires, and unburnt hydrocarbons fouling the exhaust stream. Coupled with worn traditional copper or platinum plugs with eroded gap clearances, the ignition system struggles to maintain spark kernel propagation, leading to hesitation and rough idle.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement ignition kit pairs six heavy-duty coil-on-plug assemblies with six precision iridium spark plugs. The coils feature high-conductivity internal copper windings and durable dielectric epoxy housings engineered to resist thermal degradation and prevent high-voltage arcing. The fine-wire iridium spark plugs provide superior ignitability, lower required firing voltage, and ultra-high melting point resistance for clean, continuous spark stability across the entire RPM band.\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;\"\u003e1998-2002 Mazda 626\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;\"\u003e2.5L KL-DE V6 \/ GF 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;\"\u003e170 hp \/ 165 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;\"\u003eUF406, FD502, DG500, UF-406\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1998 Mazda 626 LX, ES (2.5L V6 KL-DE)\u003c\/li\u003e\n  \u003cli\u003e1999 Mazda 626 LX, ES (2.5L V6 KL-DE)\u003c\/li\u003e\n  \u003cli\u003e2000 Mazda 626 LX, ES (2.5L V6 KL-DE)\u003c\/li\u003e\n  \u003cli\u003e2001 Mazda 626 LX, ES (2.5L V6 KL-DE)\u003c\/li\u003e\n  \u003cli\u003e2002 Mazda 626 LX, ES (2.5L V6 KL-DE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Mazda Performance Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to meet exact Japanese OEM specifications, this ignition system kit ensures factory-calibrated electrical impedance, quick throttle response, and smooth power delivery without triggering engine fault codes or hesitation.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50452215660792,"sku":"DS-E5BNQD614","price":71.95,"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-626-1998-2002-2-5l-1.jpg?v=1788720995","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-mazda-626-1998-2002-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
