The C3 Stingray ran from 1968-1982, making it the longest-running generation Corvette ever. Based on the Mako Shark II which was penned by Larry Shinoda, the C3 carried the Corvette name from the end of the muscle car era and remained successful through both gas crises of the 70s and into the 80s.

ACCEL HP Spark Plugs are made with a Copper core which is a better conductor than Platinum and Iridium. They deliver a stronger spark especially in high performance applications where high combustion pressures are present. Copper is much better at dissipating heat than other materials which lessens the chance of a misfire.
