Will ngk plugs with r hurt anything?

I got some b8es plugs wit blue letters and a r. Will it hurt to run them? I am aware the boots have restance already built in.

↑ yep, just means its a resistor plug which means it has a resister in it that eliminates radio noise that interferes with electronics. If your using an aftermarket cdi or coil then most need these but stock does not. It wont hurt it either tho.

Not a problem. I run non resistor if possible, but it probably makes no difference.
