Twin Power Ignition Coils

If you want to increase peak spark voltage on your Harley-Davidson® by 20 percent or more, you need Twin Power ignition coils. These coils have a late OEM-style molded case and are high-quality, high-voltage replacements. They're designed for 12 V Harley® ignition systems—and will improve starting, prevent high-speed misfires, and increase mileage and performance. Twin Power ignition coils may come in OEM-style cases, but it's what's inside that counts.
