Positioned directly above the cylinder head, the factory coil bodies absorb significant ambient heat, leading to internal winding fatigue and microscopic cracks in the epoxy potting. This thermal breakdown inevitably causes voltage leaks, resulting in weak spark saturation, intermittent rough idle, increased emissions, and hesitation under heavy load or towing conditions.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eEngineered to exceed factory specifications, these replacement coils utilize upgraded copper wire windings with superior conductivity and lower resistance, maximizing spark delivery to the plug. The housings are constructed from high-dielectric epoxy and thermal-resistant polymers, specifically designed to withstand extreme engine bay temperatures without cracking. A heavier gauge internal core prevents secondary voltage drop, ensuring a crisp, consistent arc. This translates to efficient combustion, smoother idle, and reliable towing capability, even in high-heat environments.\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;\"\u003e2000-2004 Toyota Tundra\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 \/ XK30 \/ XK40\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;\"\u003e190 hp \/ 220 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, C1041, GN10184\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2000 Toyota Tundra 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e2001 Toyota Tundra 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e2002 Toyota Tundra 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e2003 Toyota Tundra 3.4L V6\u003c\/li\u003e\n  \u003cli\u003e2004 Toyota Tundra 3.4L V6\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Toyota Durability Standard\u003c\/h3\u003e\n\u003cp\u003eFor a truck engineered to pull and haul, consistent spark is non-negotiable.
