you need to pair the wires with the MSD coil you will be able to gap at .065 inches or slightly above which allows for a hotter and more efficient burn without misfiring you can not do this with stock wires and coil.

benefits are

better gas mileage some have seen up to 3mpg increase
smoother through the RPM range
smoother running engine
