These spark plug wires are not ohm stable, my Harley constantly displaying error codes stating misfires in both cylinders. Upon reinstalling the stock issued Harley Davidson wires, no error codes are displayed. Both sets of wires (Sumax & stock) were tested and installed at a Harley Davidson service center, tech stated the Sumax wires are not recommended for Harley use. 2004 Harley Davidson FXDWGI.
The wires are an easy install and great fit. I little lighter than I thought , but hold there shape and color with heat and washing. Getting another set for my Street Glide!
The wires were to short for my wide glide but was what was for my bike so i had to re-route them a different way and they were just long enough to make it with nothing to spare so i cant recommend the wires .
