I ride a 2006 Harley Davidson Sportster 1200XL with a Screamin Eagle upgrade. I installed the NGK Iridium spark plugs on the recommendation of the mechanic that was doing my 10,000 mile service. Man!! Am I impressed!! Big increase in performance! Bike is running like a bat out of Hyades! :-)
Donnie (Lancaster, PA)
Great plug, I use this because my climate doesn't need cold start plugs and I don't do much high speed riding. Purchased for my K1 Gsxr 750 and they were exactly what I needed. Helped ignition and detonation made for a better ride. Easy to install took me about an hour and I was off riding.
