Mounted directly above the exhaust manifolds, the OEM coil epoxy and internal copper windings rapidly degrade over time. This thermal stress increases electrical resistance, resulting in weak spark energy during heavy engine loads. Furthermore, factory spark plug wire jackets become brittle and crack, leading to electrical arcing against the block. This cascade of failures causes P0300-series random misfire codes, rough idling, and significant horsepower loss.\u003c\/p\u003e\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis complete ignition kit remedies C5 thermal vulnerabilities using advanced insulation and upgraded internal components. The coils feature high-purity copper windings and premium dielectric epoxy to stabilize voltage output during intense heat soak. This ensures a consistent transfer of high-voltage spark energy, completely eliminating high-RPM spark blowout. Combined with heavy-duty silicone spark plug wires that resist thermal cracking, the electrical path remains completely isolated. Together with fresh spark plugs, this system restores total combustion efficiency, delivering crisp throttle response and a smoother powerband.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n\u003ctbody\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;\"\u003e1997-2004 Chevrolet Corvette (Base \u0026amp; Z06)\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;\"\u003eLS1, LS6 \/ C5 (Y-Body)\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;\"\u003e345-405 hp \/ 350-400 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;\"\u003e12558948, 12556450, D580, UF192, 5C1078\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1997 Chevrolet Corvette 5.7L V8\u003c\/li\u003e\n\u003cli\u003e1998 Chevrolet Corvette 5.7L V8\u003c\/li\u003e\n\u003cli\u003e1999 Chevrolet Corvette 5.7L V8\u003c\/li\u003e\n\u003cli\u003e2000 Chevrolet Corvette 5.7L V8\u003c\/li\u003e\n\u003cli\u003e2001 Chevrolet Corvette 5.7L V8 (Base \u0026amp; Z06)\u003c\/li\u003e\n\u003cli\u003e2002 Chevrolet Corvette 5.7L V8 (Base \u0026amp; Z06)\u003c\/li\u003e\n\u003cli\u003e2003 Chevrolet Corvette 5.7L V8 (Base \u0026amp; Z06)\u003c\/li\u003e\n\u003cli\u003e2004 Chevrolet Corvette 5.7L V8 (Base \u0026amp; Z06)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Chevrolet Performance Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered for the demands of the American V8, this ignition set restores the aggressive power delivery and raw exhaust note the C5 Corvette is known for, providing consistent firing whether on the street or the track.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50065379950840,"sku":"DS-EBI8QYVU3","price":239.95,"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-z06-1997-2004-5-7l-v8-1.webp?v=1785257006","url":"https:\/\/performancechiptuning.com\/fr\/products\/ignition-coil-spark-plugs-for-chevrolet-corvette-z06-1997-2004-5-7l-v8","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
