Great quality spark plug

These plugs are recommended for most Japanese vehicles and they seem to outlast anything I've used in any of my motorcycles . Also you don't need anti-seize thread paste these are factory coated with a special metal and recommended not to use the anti-seize

So hard to find this model of sparkplug to fit my bike. The manual says I should use this size but wasn't available anywhere in Mexico. Now the bike performs a little better than using the CPR8EA-9
