I'm planning on running Iridium Denso spark plugs with Thundervolt 50 wires in my 08 Nightster. Being that it's a hotter plug, I was wondering if I should be worried about anything or if I should be doing something before I decide to switch over to them?
Cool, thanks. My buddy just threw a 100 ci S&S in his Sportster Custom and he wasnt able to run those plugs or wires anymore. So, he just gave them to me saying that it would be a little more efficient, and just as a perk, a little added power. Wasnt sure if they would work or not. They were free, so I figured why not!
