BEEFY Review by Manchild
These are some high quality wires. Used these with my coil kit. Less resistance is better for faster spark when used with coil relocation kit. Thanks DK. (Posted on 8/27/2020)
Me Like Review by Paul

Better than stock Review by GurtSquirt
I don't know how to tell the quality of spark plugs cables by just looking at them, but I have no doubt these are a much higher quality than the OEM ones. Almost everything I've pulled off my bike felt cheaply made, and most of it has been replaced by quality parts from DK Custom. I have much more confidence in these plugs. The length is perfect too.
