Sumax 8mm Spark Plug Wires For Harley Touring And Sportster

Hot spark is critical to extracting maximum horsepower from your mill, and skinny, ragged-out stock spark plug wires are not going to move the juice from your coil into your plugs very well. Replace them with Sumax high-quality silicone-jacketed plug wires.


  • Designer plug wire sets come in distinctive, highly visible colors
  • Precut and have plug/coil boots and terminals already installed
  • Boots and wires are made from extra-high-temperature silicone, which gives protection up to 600°F
  • Spiro-Pro core provides up to 10 times the conductivity of a standard carbon-core wire
  • Low resistance means they run cooler and last 3-4 times longer than carbon-core wires
  • Designed for electronic ignitions
  • 21 1/2" & 9" Leads
  • 180° coil boot, 90° plug boot on one lead, 180° coil boot, 180° plug boot
  • Sold in pairs
  • Made in the USA

Fitment Notes & Exceptions

  • Fits bikes with coil adjacent to oil tank
