Ignition Coil & Iridium Spark Plugs & Wire Chevrolet Corvette (2014-2019) 6.2L V8

High-Output Ignition Coil & Iridium Spark Plug Kit for 2014-2019 Chevrolet Corvette

What it does: This comprehensive ignition overhaul kit replaces degraded factory coils, wires, and spark plugs to restore optimal combustion, eliminate misfires, and maximize engine performance.

The Stock Corvette C7 Ignition Weakness

The factory C7 ignition system is subjected to extreme underhood temperatures, especially during aggressive driving or track sessions. Over time, continuous thermal cycling breaks down the OEM spark plug wire insulation and the internal epoxy potting of the factory coils. This thermal degradation drastically increases secondary electrical resistance, resulting in weak spark delivery and spark blowout under heavy load. Drivers often experience cylinder misfires, poor fuel economy, rough idling, engine hesitation, and the triggering of Check Engine (CEL) and VSC warning lights as unburnt fuel throws off O2 sensor readings.

The Engineering Solution

This complete kit is engineered to resolve C7 misfires by upgrading the entire spark delivery path. The UF742 replacement coils feature premium internal copper windings and robust epoxy construction, producing up to 26,000V with a 61:1 turn ratio—delivering 20% more spark energy than standard OE replacements. To ensure this voltage reaches the cylinder without arcing, the kit includes 8mm thick, high-temperature silicone spark plug wires equipped with dedicated heat shields to survive the blistering heat of the exhaust manifolds. Finally, the included 41-114 iridium spark plugs utilize an ultra-fine, high-melting-point rare-metal electrode, providing exceptional conductivity and a highly focused spark for complete fuel atomization.
