Ignition Coil & Spark Plug for Chevy Corvette (2005-2016) V8 (Round Style)

High-Energy Ignition Coil & Spark Plug Set for 2005-2016 Chevrolet Corvette

What it Does: Replaces deteriorating factory ignition components with a high-output, 32,000-volt coil pack system and matched wires to ensure consistent spark delivery and eliminate misfires under heavy engine load.

The Stock Corvette Ignition Breakdown

OEM coil packs and spark plug wires in the C6 and early C7 V8s are subjected to extreme thermal stress due to the confined engine bay and close proximity to the exhaust manifolds. Over time, the factory epoxy encapsulation degrades from repeated heat cycling, leading to internal resistance changes, micro-arcing, and intermittent misfires under heavy load. The stock wire boots also dry-rot and crack over high mileage, compromising spark isolation and robbing the LS and LT powerplants of crucial ignition energy. This degradation results in sluggish throttle response, poor combustion efficiency, and rough idle conditions.

The Engineering Solution

This direct-replacement ignition package upgrades the factory system with high-output round-style D514A/UF414 coils, delivering up to 20% more discharge energy than standard OE specifications. Engineered with premium internal copper windings, durable epoxy encapsulation, and a 61:1 turns ratio, these coils generate a maximum of 32,000 volts for a highly dense, reliable spark. Paired with exact-match 41962 spark plugs and low-resistance 748UU spark plug wires, the kit minimizes voltage drop and combats heat soak. The robust silicone construction of the wire boots ensures exceptional dielectric strength, translating to restored horsepower, smoother idle, and consistent wide-open throttle performance. Note: This kit is exclusively engineered for vehicles equipped with round-style coils; it is not compatible with square-body D510C coils.
