Long known for their Harley-Davidson spark plug sets, Sumax now makes them for 2008 and later Victory Motorcycles. These made-in-the-U.S.A. custom spark plug wires were designed by Sumax and are made by Taylor. They feature a Pro 8MM Spiro Pro core with Pro Comp Racing Plug Boots. You can get them in a variety of colors to match your bike, including: black, red, blue, yellow, orange, green, white, purple and grey. The wire sets require no terminating; they are ready to plug in and ride. Sumax’s Thundervolt 50 series High Performance 8.2mm and 10.4mm wires are endorsed by Loydz Motorworkz, the Victory Performance gurus. This product is distributed by Lemans, Drag Specialties, Tucker Rocky, Biker’s Choice, and Lloydz Motorworkz.
