Over years of severe thermal cycling, the OEM epoxy insulating the internal windings degrades. This deterioration leads to micro-cracking and massive internal resistance spikes. The resulting symptoms are weak spark, rough idle, increased fuel consumption, and under-load misfires. This is especially prevalent when heat soak conditions elevate under-hood temperatures during off-road crawling or extended towing applications.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThese performance replacement coils are constructed with upgraded primary and secondary copper windings to maximize voltage output and drastically reduce cycle recovery time. The precision-wound cores are housed in a high-dielectric polymer casing sealed with heavy-duty, thermal-resistant epoxy. This effectively prevents moisture intrusion and withstands extreme engine bay temperatures. Designed as a direct bolt-on upgrade, they integrate perfectly with the factory female wiring harness and three-terminal interface, ensuring zero voltage leakage and a stable, high-intensity spark across the entire RPM range.\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;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1996-2002 Toyota 4Runner\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e5VZ-FE \/ N180\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e183 hp \/ 217 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF156 \/ 9091902212\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e1996-2002 Toyota 4Runner 3.4L V6 (Front Placement)\u003c\/li\u003e\n    \u003cli\u003eInterchange Part Numbers: UF156, 9091902212, C1041, E679, 178-8274, GN10184, IC223, 348L, 48983, U4016, 450002, IGC0119, 297007951, C-509, 88921337, E589, 1IC134, 50050, 36-8014, 5015, 2505-34660\u003c\/li\u003e\n    \u003cli\u003eSuperseded Part Numbers: 921-2009, 5C1308, IC223SB, UF156T, 673-1201, 23-0365, 52-1519\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Toyota Durability Standard\u003c\/h3\u003e\n  \u003cp\u003eThe Toyota N180 standard demands relentless reliability on the trail.
