Constant exposure to high engine bay temperatures causes the internal coil epoxy to break down and the secondary windings to develop excessive resistance. This chronic heat soak leads to weak spark propagation, intermittent misfires under load, and reduced fuel efficiency. Furthermore, degraded factory spark plug wires often experience dielectric breakdown, allowing voltage to arc to the block rather than reaching the spark plug, resulting in a severe loss of power and poor drivability.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive tune-up kit addresses OEM deficiencies through upgraded materials and optimized coil internals. The round-style UF414\/D514A replacement coils feature a heavy-duty epoxy construction and high-grade copper wire primary\/secondary windings with a 61:1 turns ratio. This maximizes thermal resilience and lowers primary resistance to 0.660 ohms. Capable of generating a maximum voltage of 32,000 V, these coils deliver 20% more energy than standard OEM units for a stronger, more consistent spark. Paired with exact-match spark plugs (41962) and low-resistance 748UU plug wires, this system ensures maximum voltage transfer and complete combustion, restoring lost torque and eliminating rough idle. \u003cem\u003eNote: Specifically engineered for GM V8s utilizing the round-style coils; incompatible with square-style (UF413\/D510C) setups.\u003c\/em\u003e\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;\"\u003e2008-2016 Chevrolet Express 1500 \/ 2500 \/ 3500 (Round Coil Only)\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;\"\u003eGM Gen IV Vortec V8 (4.8L, 5.3L, 6.0L) \/ GMT610\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;\"\u003e~280-342 hp \/ ~295-373 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;\"\u003eUF414, D514A, 748UU, 41962\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eCadillac Escalade (Round Coil Equipped)\u003c\/li\u003e\n  \u003cli\u003eChevrolet Avalanche (Round Coil Equipped)\u003c\/li\u003e\n  \u003cli\u003eChevrolet Express 1500 \/ 2500 \/ 3500 (Round Coil Equipped)\u003c\/li\u003e\n  \u003cli\u003eChevrolet Silverado (Round Coil Equipped)\u003c\/li\u003e\n  \u003cli\u003eChevrolet Suburban (Round Coil Equipped)\u003c\/li\u003e\n  \u003cli\u003eChevrolet Tahoe (Round Coil Equipped)\u003c\/li\u003e\n  \u003cli\u003eChevrolet Trailblazer (Round Coil Equipped)\u003c\/li\u003e\n  \u003cli\u003eGMC Savana (Round Coil Equipped)\u003c\/li\u003e\n  \u003cli\u003eGMC Yukon (Round Coil Equipped)\u003c\/li\u003e\n  \u003cli\u003eHummer H3 (Round Coil Equipped)\u003c\/li\u003e\n  \u003cli\u003e\u003cem\u003eNote: Replaces OEM Part Numbers C1512, D514A, UF414, 5C1555, E894, 52-1820, IC534, 12573190, GN10165, 12570616, 12611424, 1788407.\u003c\/em\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chevrolet Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for the demands of hauling and fleet utility, this ignition upgrade restores the steadfast reliability and towing capability expected from your GM heavy-duty powertrain, ensuring smooth power delivery and maximizing uptime.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":49710973223160,"sku":"DS-EZBDFG3YU","price":179.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plug-for-chevy-express-1500-2500-3500-van-2008-2016-v8-round-style-1.jpg?v=1782796172","url":"https:\/\/performancechiptuning.com\/es\/products\/ignition-coil-spark-plug-for-chevy-express-1500-2500-3500-van-2008-2016-v8-round-style","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
