In terms of pure performance, the Buick Regal probably doesn't rank highly on most people's list. However, it was built on the versatile G-Body platform which allows for various engine swaps and a litany of performance parts to bolt right in. GM knew this too as the humble Regal was the base for the legendary Buick Grand National.

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.
