Constant engine bay heat cycling severely degrades the factory molded thermoplastic housings, resulting in micro-fractures, secondary winding flashover, and internal resistance spikes. Combined with plug electrode erosion across eight separate spark gaps, weakened ignition delivery results in incomplete flame propagation, hesitation under throttle, and unburnt hydrocarbon buildup in the exhaust stream.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-replacement kit addresses high-voltage breakdown with high-grade PBT composite coil housings and premium epoxy potting compound to prevent dielectric puncture and moisture intrusion. Balanced copper primary and secondary windings maintain precise dwell characteristics and high millijoule spark discharge across both coil packs. Paired with eight heat-range matched, pre-gapped spark plugs, this kit restores reliable dual-plug flame kernel propagation to maintain combustion efficiency under payload strain.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100% style=\" border-collapse: collapse border: solid font-size: min-width:\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1998-2001 Mazda B-Series B2500 (2.5L I4)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003e2.5L Lima OHC\u003c\/strong\u003e \/ \u003cstrong\u003ePN105\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e119 hp \/ 146 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eFD487\u003c\/strong\u003e, \u003cstrong\u003eFD490\u003c\/strong\u003e, \u003cstrong\u003e1E05-18-100\u003c\/strong\u003e, \u003cstrong\u003eF37Z-12029-A\u003c\/strong\u003e, \u003cstrong\u003eF5LU-12029-AA\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1998 Mazda B2500 2.5L L4 Regular Cab \u0026amp; Extended Cab\u003c\/li\u003e\n  \u003cli\u003e1999 Mazda B2500 2.5L L4 Regular Cab \u0026amp; Extended Cab\u003c\/li\u003e\n  \u003cli\u003e2000 Mazda B2500 2.5L L4 Regular Cab \u0026amp; Extended Cab\u003c\/li\u003e\n  \u003cli\u003e2001 Mazda B2500 2.5L L4 Regular Cab \u0026amp; Extended Cab\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the PN105 B-Series B2500?\u003c\/h4\u003e\n\u003cp\u003eYes, this kit is engineered as a direct replacement for the 1998-2001 Mazda B-Series B2500 equipped with the 2.5L Lima four-cylinder engine.\u003c\/p\u003e\n\n\u003ch4\u003eWhy does this 4-cylinder engine require eight spark plugs?\u003c\/h4\u003e\n\u003cp\u003eThe 2.5L Lima head utilizes dual spark plugs per cylinder fired in waste-spark sequence to speed flame propagation, improve low-end torque, and minimize tailpipe emissions.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mazda Workhorse Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt for the demands of utility hauling and daily work, this ignition renewal restores crisp throttle response, stabilizes heavy-load pulling power, and eliminates unburnt fuel wash to protect your catalytic converter for miles to come.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67518836703480,"sku":"DS-EGJUKRNA0","price":137.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-mazda-b2500-1998-2001-2-5l-1.jpg?v=1790370855","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-spark-plugs-for-mazda-b2500-1998-2001-2-5l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
