Are there any performance gains to the 3 cylinder 120 engines using the cr10ek plugs?

Do they help gas mileage as well?

I thought one of the mags did a test on the cr10ek plug and found no evidence of any horse power gain. It is just a mith

no mith, try running against one with the cr10ek's and you keep you stock ones , you'll be ordering them quickly

It's been dyno proven over and over.

Why would yamaha not put these in from stock if they make their sleds run that much better, is there a chance that the can harm or lower the life of the engine? You think they would run the best possible plugs for the best performance.
