Over years of thermal cycling, the OEM coil casings develop microscopic epoxy fissures and dielectric breakdown in the primary and secondary copper windings. This internal winding breakdown causes severe voltage drop, carbon tracking, and intermittent cylinder misfires—especially when pulling a load or climbing under low-RPM high-manifold pressure. Compounding this, aged factory plugs suffer from widened electrode gaps due to dual-strike erosion, forcing the degrading coils to demand excessive firing voltage that triggers ignition blow-out and raw fuel dumping into the exhaust stream.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit replaces all primary wear points in one matched package. The two direct-fit ignition coils are built with high-dielectric PBT thermoplastic housings and vacuum-poured epoxy insulation to withstand continuous underhood heat soak without dielectric punch-through. Premium magnetic copper wire windings provide stable primary-to-secondary turns ratios to ensure peak secondary discharge exceeding 35,000 volts. Paired with eight precision-gapped, corrosion-plated spark plugs featuring high-alumina ceramic ribs, this kit restores consistent flame-front kernel development across both the intake-side and exhaust-side combustion zones, stabilizing engine idle and eliminating unburned hydrocarbon emissions.\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;\"\u003e1994-1997 Mazda B-Series,B2300\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;\"\u003e2.3L Lima OHC \/ UN Platform\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;\"\u003e112 hp \/ 135 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\u003eF37Z12029A\u003c\/strong\u003e, \u003cstrong\u003e1E05-18-100\u003c\/strong\u003e, \u003cstrong\u003eF5OU-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\u003e1994 Mazda B2300 Base \/ SE 2.3L L4\u003c\/li\u003e\n  \u003cli\u003e1995 Mazda B2300 Base \/ SE 2.3L L4\u003c\/li\u003e\n  \u003cli\u003e1996 Mazda B2300 Base \/ SE 2.3L L4\u003c\/li\u003e\n  \u003cli\u003e1997 Mazda B2300 Base \/ SE 2.3L L4\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the UN Platform B-Series,B2300?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1994-1997 Mazda B-Series,B2300 equipped with the 2.3L Lima OHC engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does this 4-cylinder engine require eight spark plugs and two coils?\u003c\/strong\u003e\u003cbr\u003e The 2.3L Lima engine utilizes a dual-plug head design with two spark plugs per cylinder fired in waste-spark sequence to ensure complete fuel burn, curb tailpipe emissions, and suppress combustion knock.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mazda Workhorse Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for real-world utility, your B2300 relies on low-end torque and bulletproof combustion efficiency to haul payload and tackle rugged job sites without missing a beat.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50625825308920,"sku":"DS-EDCBTL1I7","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-b2300-1994-1997-2-3l-1.jpg?v=1790351977","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-spark-plugs-for-mazda-b2300-1994-1997-2-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
