Over time, internal wire insulation fractures under relentless heat soak, yielding intermittent arc leaks and weak spark output. In tandem with natural electrode erosion on aging spark plugs, high circuit resistance strains ignition drivers, causing hesitations, erratic idle, and partial fuel burn across the \u003cstrong\u003eLT1\u003c\/strong\u003e cylinder banks.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis replacement kit pairs high-dielectric insulated coils with high-grade NGK spark plugs engineered to withstand high thermal loads and resist carbon fouling. Premium internal winding architecture prevents voltage drop under load, ensuring consistent secondary voltage delivery directly through to the plug tip. By replacing degraded components with matching factory-spec parts, this direct-fit system stabilizes ignition timing, lowers emissions, and restores crisp throttle response across the entire rev range.\u003c\/p\u003e\n\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e3 x Ignition Coils\u003c\/li\u003e\n  \u003cli\u003e6 x NGK Spark Plugs\u003c\/li\u003e\n\u003c\/ul\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;\"\u003e1992-1995 Chevrolet Corvette\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;\"\u003e\n\u003cstrong\u003eLT1\u003c\/strong\u003e 5.7L \/ \u003cstrong\u003eC4\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;\"\u003e300 hp \/ 340 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\u003eD546\u003c\/strong\u003e, \u003cstrong\u003e5C1077\u003c\/strong\u003e, \u003cstrong\u003eE219\u003c\/strong\u003e, \u003cstrong\u003e52-1693\u003c\/strong\u003e, \u003cstrong\u003eIC406\u003c\/strong\u003e, \u003cstrong\u003e1106008\u003c\/strong\u003e, \u003cstrong\u003eDR-47\u003c\/strong\u003e, \u003cstrong\u003e1103646\u003c\/strong\u003e, \u003cstrong\u003e11037\u003c\/strong\u003e, \u003cstrong\u003eDR39\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\u003e1992-1995 Chevrolet Corvette 5.7L V8\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions \u0026amp; Fitment Warnings\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the C4 Corvette?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1992-1995 Chevrolet Corvette equipped with the \u003cstrong\u003eLT1\u003c\/strong\u003e 5.7L engine. \u003cstrong\u003eNote: Spark plug wires are not included with this kit.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003ch4\u003eWhat are the critical installation precautions for this kit?\u003c\/h4\u003e\n\u003cp\u003eAlways verify plug gaps against factory service manual specifications, torque plugs to factory spec to avoid damaging cylinder head threads, and avoid overtightening coil mounting hardware.\u003c\/p\u003e\n\n\u003ch3\u003eThe Chevrolet Performance Caliber\u003c\/h3\u003e\n\u003cp\u003ePreserve the raw output and high-revving muscle of your \u003cstrong\u003eLT1\u003c\/strong\u003e small block with dependable ignition components designed to deliver consistent, uninterrupted spark under wide-open throttle.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67561486778616,"sku":"DS-EIUHW4BWG","price":109.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-spark-plugs-for-chevrolet-corvette-1992-1995-5-7l-1.jpg?v=1790964210","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-spark-plugs-for-chevrolet-corvette-1992-1995-5-7l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
