You bought FLO Headworks Dual Plug process, plus the accompanying Ignition and Wire Kit, to eliminate deadly detonation from your Harley’s engine.

Now for the third and final element, created for 1999 and later Twin Cams: FLO Headworks Dual Coil Kit, to create the voltage your dual-plug system needs.

These coils put out the 15,000 volts required to jump a half-inch gap. The kit comes complete with coil bracket, black 7mm suppression spark plug wires, cut to correct length with boots to fit over the coil end, and Sparky brand plug terminal made of black neoprene—all watertight and easy to install.

Installation instructions with wiring diagram are included.

Our work and products are guaranteed for one year. For an estimate on your particular application contact us directly by telephone at 805-481-6300. You can e-mail us.
