Looking for some yellow spark plug wires for my 07 street bob. I don't know much about them, is there a huge difference between brands? Should I get the 8mm ones, or go bigger? Do they make any difference in performance?I checked on screaming eagle wires, but I couldn't find yellow ones. Any help would be great!!!!!!!
I emailed Sumax and here's what they said... Question; I have a 07 FLHTCUI and I was checking out your wires but as I understand it there an Ion sensor built into the HD spark plug wires, what can you tell me about your wires, which wires should I be looking at? Thanks Answer; All of our spiro pro wires have been proven compatible with all HD ignitions. If you are looking for an excellent replacement but want to add color, our 8mm wires will do the trick. If you are looking for enhanced performance our Thundervolt wires will fit the bill. Purchase a custom set that is ready to plug in...[/align]Max[/align]
