Good sparkplugs. These were OEM on my bike, but after 20K miles definitely need replacement. After I installed the new spark plugs I could tell the difference just in the sound of the engine - smoother, deeper sound. Performance wise, there was a very small increase in the acceleration and a large decrease in backfire. No issues with fit or installation. Highly recommend these.
GREAT PRICE, OEM PERFORMANCE!,
