I just installed these yesterday and went for a ride.  It may be my imagination, but my "seat of the pants dyno" said I had MORE power!  They look good too!  Thanks!  -Jimmy

Great product Review by BikerScum
Great wires, easy to install and excellent performance so far. I like the performance look too, but that don’t get you home. (Posted on 1/11/2022)
Great Spark Plug Wires Review by TSnOKC
These wires were super easy to cut and crimp. I was a little hesitant about doing this myself, but the included instructions were simple to read and understand. They work perfectly and look great. Also, the customer service with DK Customs is second to none. (Posted on 9/2/2020)
Coil relocate kit/plug wires Review by Preacher
Excellent services... couldn’t ask for anything better... God bless. (Posted on 8/6/2020)
Huge improvement over stock Review by Phillip
The difference in performance between spark plugs wires is negligible. ( Losing 10 lb of weight is most likely going to make your Harley faster) However, on a Harley the wires are on prominent display. Wimpy stock wires look anemic compared to these "performance" wires. The fatter wires make your bike LOOK like it is more powerful. That difference is worth every penny. (Posted on 6/10/2020)
Best wires for your $$$$ Review by Damagecase
High quality wire and premium boot ends. Terminals exceed H-D oem. No better value on the market, in my opinion. (Posted on 8/9/2019)
