Subjected to sustained underhood heat cycling, the stock housing develops microscopic dielectric fissures, causing high-voltage leakage, secondary winding resistance drift, and intermittent spark blowout under load. Compounding this, factory copper or standard platinum plugs suffer gap erosion and carbon fouling, escalating resistance demands on the coil and triggering P0300 through P0306 DTC misfire codes, rough idling, and unburnt fuel dilution in the exhaust stream.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit resolves ignition loss by pairing a high-dielectric replacement coil pack with fine-wire iridium spark plugs. The ignition coil features reinforced thermoplastic casing and vacuum-impregnated internal windings to resist thermal shock and electrical tracking under severe towing loads. The included iridium spark plugs utilize ultra-dense laser-welded fine-wire center electrodes, requiring significantly lower ionization voltage to initiate arc transfer across combustion chambers. This design resists arc erosion, prevents quenching, and maintains consistent flame-front kernel propagation under variable manifold pressures.\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; margin-bottom: 20px;\"\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;\"\u003e1998-2000 Ford F-150\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\u003e4.2L Essex V6\u003c\/strong\u003e \/ \u003cstrong\u003ePN96\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;\"\u003e205 hp \/ 255 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\u003e12597745\u003c\/strong\u003e, \u003cstrong\u003eFD488\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1998 Ford F-150 (Base, XL, XLT) 4.2L V6 Essex\u003c\/li\u003e\n  \u003cli\u003e1999 Ford F-150 (Base, XL, XLT) 4.2L V6 Essex\u003c\/li\u003e\n  \u003cli\u003e2000 Ford F-150 (Base, XL, XLT) 4.2L V6 Essex\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the PN96 F-150?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1998-2000 Ford F-150 equipped with the \u003cstrong\u003e4.2L Essex V6\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the iridium spark plugs pre-gapped for the 4.2L Essex V6?\u003c\/strong\u003e\u003cbr\u003e Plugs arrive factory-gapped to OEM specification, though verifying clearance with a feeler gauge prior to torquing is standard practice.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Workhorse Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle grueling payload and towing demands, this ignition upgrade restores low-end torque delivery, stabilizes combustion under load, and ensures dependable all-weather cold-cranking reliability.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50594183610616,"sku":"DS-EHFODF7UE","price":79.95,"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-ford-f-150-1998-2000-4-2l-1.jpg?v=1790057805","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-and-iridium-spark-plugs-for-ford-f-150-1998-2000-4-2l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
