As thermal stress breaks down the coil's primary and secondary winding laminations, internal resistance increases, creating weak spark output and intermittent misfires (DTC P0300). Combined with electrode gap erosion on aged spark plugs, the elevated voltage demand strains the aging ignition system, causing hesitation under load, poor fuel economy, and incomplete combustion in \u003cstrong\u003eVortec\u003c\/strong\u003e engines.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis kit features a direct-fit, high-dielectric epoxy-molded ignition coil engineered to match factory dwell times while resisting thermal vibration. Wound with heavy-gauge copper magnet wire, it produces the high-energy discharge required to ignite air-fuel mixtures reliably across all RPM bands. The included high-conductivity spark plugs feature anti-corrosion nickel-plated shells, thermal-resistant ceramic insulators, and durable copper cores designed for stable gap retention and rapid heat dissipation under heavy towing demands.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\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;\"\u003e1996-1999 Chevrolet C1500 \/ K1500\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;\"\u003e4.3L (\u003cstrong\u003eL35\u003c\/strong\u003e), 5.0L (\u003cstrong\u003eL30\u003c\/strong\u003e), 5.7L (\u003cstrong\u003eL31\u003c\/strong\u003e) \/ \u003cstrong\u003eGMT400\u003c\/strong\u003e\n\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;\"\u003e200-255 hp \/ 250-330 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;\"\u003e\n\u003cstrong\u003e10489421\u003c\/strong\u003e, \u003cstrong\u003e19207138\u003c\/strong\u003e, \u003cstrong\u003e19418996\u003c\/strong\u003e, \u003cstrong\u003eD577\u003c\/strong\u003e, \u003cstrong\u003eDR49\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1996-1998 Chevrolet C1500 4.3L V6\u003c\/li\u003e\n  \u003cli\u003e1996-1999 Chevrolet C1500 5.0L V8\u003c\/li\u003e\n  \u003cli\u003e1996-1999 Chevrolet C1500 5.7L V8\u003c\/li\u003e\n  \u003cli\u003e1996-1998 Chevrolet K1500 4.3L V6\u003c\/li\u003e\n  \u003cli\u003e1996-1999 Chevrolet K1500 5.0L V8\u003c\/li\u003e\n  \u003cli\u003e1996-1999 Chevrolet K1500 5.7L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp style=\"font-size: 13px; color: #555;\"\u003e\u003cem\u003eNote: 4.3L V6 applications utilize 6 of the 8 included spark plugs; V8 engines use all 8.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the GMT400 C\/K Trucks?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 1996-1999 Chevrolet C\/K Trucks equipped with the \u003cstrong\u003eL35\u003c\/strong\u003e, \u003cstrong\u003eL30\u003c\/strong\u003e, or \u003cstrong\u003eL31\u003c\/strong\u003e Vortec engines.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShould the spark plug gaps be verified prior to installation?\u003c\/strong\u003e\u003cbr\u003e Yes, always verify and set the spark plug gap to the factory specification of 0.060 inches using a feeler gauge prior to installation.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Truck Durability Standard\u003c\/h3\u003e\n\u003cp\u003eBuilt to handle prolonged operating hours and high-load hauling cycles, this ignition assembly delivers the spark stability required to keep your GM small-block or V6 powertrain running cleanly under demanding towing conditions.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50625994195192,"sku":"DS-E401BDRJK","price":74.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-chevrolet-c1500-k1500-1996-1999-4-3l-5-0l-5-7l-1.jpg?v=1790353251","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-spark-plugs-for-chevrolet-c1500-k1500-1996-1999-4-3l-5-0l-5-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
