KX250 spark plug

I wonder Y there is a NGK B8ES plug in my kx250 and its suppose to have a NGK BR8EIX in it. Its an NGK iridium also. Anybody know if B8ES is just as good.

I'm guessing its in there because its cheaper lol

I know on 450R's... YFZ450R's... all those, you can buy an iridium plug which is like $16 or you can use a $5 regular plug.

I run whatever works in my machines. I dont see any iridium plug making a big enough difference to spend 3x what i could buy a regular for.

If thats what your asking.

If it works run it. Don't think it will hurt it.

Iridium is overrated.
