Decades of engine bay thermal cycling degrade the internal copper windings and epoxy resin insulation of the factory coil, leading to core saturation breakdown, dielectric punch-through, and intermittent misfires under load. Compounding this, worn spark plugs exhibit eroded nickel electrodes and widened gaps, which spikes the secondary voltage requirement, overworking the ignition coil and causing hesitations, poor fuel economy, and unburnt hydrocarbon emissions.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis direct-fit ignition refresh kit resolves high-voltage transfer loss by pairing a robust external ignition coil with four matched spark plugs. The replacement coil utilizes premium magnetic copper wire windings and high-dielectric epoxy potting to handle thermal stress without arc-over or insulation failure. Matched to factory heat ranges, the included spark plugs feature anti-corrosive plating, high-alumina ceramic insulators, and precision-gapped ground electrodes. This setup guarantees stable arc delivery across the full RPM band, preventing quench-out and restoring consistent cylinder pressures.\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: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e1993-1997 Nissan Altima\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;\"\u003eKA24DE \/ U13\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;\"\u003e150 hp \/ 154 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;\"\u003e224481E410, 224481E400, 2243365Y10, 2243355Y01, UF118, UF-118, 2243355Y00, 2243353F00, 224331E420, 224331E400\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\u003e1993 Nissan Altima (XE, GXE, SE, GLE) 2.4L L4\u003c\/li\u003e\n  \u003cli\u003e1994 Nissan Altima (XE, GXE, SE, GLE) 2.4L L4\u003c\/li\u003e\n  \u003cli\u003e1995 Nissan Altima (XE, GXE, SE, GLE) 2.4L L4\u003c\/li\u003e\n  \u003cli\u003e1996 Nissan Altima (XE, GXE, SE, GLE) 2.4L L4\u003c\/li\u003e\n  \u003cli\u003e1997 Nissan Altima (XE, GXE, SE, GLE) 2.4L L4\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the U13 Altima?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1993-1997 Nissan Altima equipped with the \u003cstrong\u003eKA24DE\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eAre spark plug wires included with this ignition kit?\u003c\/h4\u003e\n\u003cp\u003eNo, this kit includes one ignition coil and four spark plugs; reuse your existing high-tension leads or install new OEM-spec plug wires.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan JDM Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered to handle the demanding ignition cycles of high-revving Japanese DOHC platforms, this ignition assembly delivers repeatable spark energy and factory-spec combustion stability without throwing check engine codes.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67518851023096,"sku":"DS-EJ303AH6V","price":54.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-nissan-altima-1993-1997-2-4l-1.jpg?v=1790371011","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-spark-plugs-for-nissan-altima-1993-1997-2-4l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
