9 MM Gun High Performance Spark Plug Wires (Kit)

9 MM Firepower with Killer Looks

All wires fire intermittently no matter what coil or ignition you may have. That is why you see carbon on your plugs. Our 9MM Firepower wires with 40 ohms of resistance provide a solid stream of fire power eliminating the carbon on your plugs. This results in more horsepower, more torque and better mileage. Your bike will start and run better than ever before! They are compatible with all Harley Davidson® ignition systems.

You have a choice of Custom Fit Sets for your Harley Davidson® model or Universal Sets where you terminate to your desired length.

THE ULTIMATE PERFORMANCE AND RACING IGNITION WIRE AVAILABLE!

Sumax Taylor Cable’s lowest resistance wire – 9mm diameter and only 40-OHMS per foot = more horse power… torque… spark energy.

  • 40 Ohm/ft Ferrite Spiral-Wound coated core blend of exclusive copper/nickel alloy bonded by a conductive acrylic cover.
  • Exclusive 100% ZIMPLEX® silicone outer jacket provides additional heat and abrasion protection up to 600 degrees Fahrenheit and 102,000 volts dielectric strength, a must for the extreme conditions of open wheel racing and under hood temperatures.
