Constant underhood heat cycling degrades internal epoxy insulation and primary windings inside the coil, leading to carbon tracking, secondary voltage leaks, and intermittent misfires under heavy throttle. Simultaneously, high-mileage copper or worn platinum plugs develop widened electrode gaps that demand higher firing voltage than degraded coils can provide, choking off combustion efficiency, fouling catalytic converters, and triggering P0300 through P0304 fault codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis service kit resolves weak spark events by pairing a heavy-duty direct replacement ignition coil with precision fine-wire iridium spark plugs. The ignition coil features high-dielectric epoxy potting, thermal-resistant magnetic core laminations, and reinforced primary\/secondary copper windings designed to resist internal insulation breakdown. Matched with fine-wire iridium electrodes requiring lower strike voltages, this assembly provides instantaneous arc initiation, superior quenching resistance, and high resistance to spark wash during high-load hauling conditions. Replacing these components as a matched unit stabilizes dwell time and maintains stoichiometric combustion efficiency across the entire RPM band.\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;\"\u003e2001-2004 Nissan Frontier\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 \/ D22\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;\"\u003e143 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;\"\u003eUF731, 224334M000, 22433F4302, 7090, 5C1661\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2001 Nissan Frontier Base \/ XE (2.4L L4 KA24DE)\u003c\/li\u003e\n  \u003cli\u003e2002 Nissan Frontier Base \/ XE (2.4L L4 KA24DE)\u003c\/li\u003e\n  \u003cli\u003e2003 Nissan Frontier Base \/ XE (2.4L L4 KA24DE)\u003c\/li\u003e\n  \u003cli\u003e2004 Nissan Frontier Base \/ XE (2.4L L4 KA24DE)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the D22 Frontier?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2001-2004 Nissan Frontier equipped with the \u003cstrong\u003eKA24DE\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre these spark plugs pre-gapped for installation?\u003c\/strong\u003e\u003cbr\u003e Yes, the iridium plugs come pre-gapped, though verifying gap against factory \u003cstrong\u003eKA24DE\u003c\/strong\u003e service specifications prior to installation is recommended.\u003c\/p\u003e\n\n\u003ch3\u003eThe Nissan Work-Ready Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle sustained duty cycles, this ignition package ensures consistent spark delivery under heavy payload hauling, steep incline towing, and rough terrain operations.
