Positioned directly above the exhaust manifolds, the stock epoxy potting dries out and cracks from continuous heat soak cycles. This leads to internal arcing, weak spark delivery, and parasitic voltage leaks. Under towing conditions or heavy throttle, this weak spark translates to noticeable hesitation, reduced fuel economy, and dreaded P0300-series random misfire codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThese high-performance ignition coils are constructed using upgraded magnetic steel cores and optimized copper wire windings to step up voltage output and maintain faster dwell recovery times. The housing is molded from high-dielectric epoxy and advanced thermal-resistant polymer, specifically formulated to withstand the extreme under-hood temperatures of the GMT800 engine bay. By providing a stronger, more complete combustion event, these coils optimize fuel burn, stabilize idle vacuum, and restore the low-end torque essential for moving heavy SUV chassis. The electronic blade-type terminals ensure a secure, corrosion-resistant connection to the factory wiring harness.\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;\"\u003e2000-2006 Chevrolet Tahoe\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;\"\u003eVortec 4.8L (LR4) \u0026amp; 5.3L (LM7\/L59) \/ GMT800\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;\"\u003e275-295 hp \/ 290-335 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;\"\u003eD585, UF262, 10457730, 19005218, 920-1020, GN10119\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2000-2006 Chevrolet Tahoe 4.8L V8\u003c\/li\u003e\n  \u003cli\u003e2000-2006 Chevrolet Tahoe 5.3L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chevrolet Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt for the demanding environments that GMT800 trucks operate in, these ignition coils guarantee the reliability needed for heavy towing and daily hauling without triggering annoying Check Engine Lights.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":48234277961976,"sku":"DS-ECZ6X4ZH3","price":139.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/Ignition-Chevy-V8.jpg?v=1776103425","url":"https:\/\/performancechiptuning.com\/products\/high-performance-ignition-coils-for-chevrolet-tahoe-2000-2006-4-8l-5-3l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
