The coil assembly features premium silicon magnetic steel laminations and high-temperature copper windings sealed in vacuum-poured dielectric epoxy to prevent internal arcing under sustained dwell times. The included iridium-tipped spark plugs feature an erosion-resistant fine-wire center electrode, drastically reducing required firing voltage and delivering an intense, concentrated flame kernel for clean burn cycles under heavy throttle.\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;\"\u003e1998-2008 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;\"\u003eEssex 4.2L V6 \/ PN96 \u0026amp; P221\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;\"\u003e202 hp \/ 260 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;\"\u003e12597745, FD498, KIN119795TOP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1998-2003 Ford F-150 (XL, XLT) 4.2L V6\u003c\/li\u003e\n  \u003cli\u003e2004 Ford F-150 Heritage 4.2L V6\u003c\/li\u003e\n  \u003cli\u003e2004-2008 Ford F-150 (XL, STX, XLT) 4.2L V6\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 and P221 F-150?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1998-2008 Ford F-150 equipped with the Essex 4.2L engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo these iridium spark plugs require manual gapping before installation?\u003c\/strong\u003e\u003cbr\u003e Plugs arrive pre-gapped to factory specifications, though confirming electrode clearance with a wire-type gauge prior to threading into the aluminum heads is standard practice.\u003c\/p\u003e\n\n\u003ch3\u003eThe Ford Workhorse Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle rigorous payload demands, high-ambient heat cycles, and severe-duty towing, this ignition kit provides clean, sustained arc transfer to keep your truck running reliably under demanding working conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50594210873592,"sku":"DS-EXE2OXHAM","price":69.95,"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-150-1998-2008-4-2l-1.jpg?v=1790058060","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-and-iridium-spark-plugs-for-ford-f-150-1998-2008-4-2l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
