1997-2013 ACCEL HP Copper Core Spark Plugs
When you’re asking more from your Corvette than factory cruising duty, your ignition system has to keep up. These ACCEL HP Copper Core spark plugs are built for 1997-2013 Corvettes that see real driving, whether that’s hard street miles or track time. Copper conducts electricity better than platinum or iridium, which means a stronger, more consistent spark when cylinder pressures climb. Better heat dissipation helps prevent misfires, keeps combustion stable, and protects performance under load. The C-cut design unshrouds the spark kernel for a cleaner burn, and unlike exotic metal plugs, these are fully gapable so you can dial them in exactly how your setup demands. Add in machine-rolled threads for proper torque retention and smooth installation, and you get a spark plug that does its job quietly and reliably, exactly what a Corvette owner expects.
