A strong spark is the foundation of a high-horsepower engine. If your ignition wires are leaking voltage or have high resistance, you are leaving power on the table. The FAST Firewire set ensures that every bit of energy from your coil reaches the spark plug, resulting in cleaner combustion, better throttle response, and increased power across the RPM range. These wires are finished in a sleek black, providing a clean, professional look under the hood. Trust your ignition needs to the experts at GGCRACING.
