Could anyone give me a cross reference # on a good plug (ie:Bosch) for my Prairie 650 from the current ngk-cr7e. Went to three parts house and all they could come up with was a champion plug...THANKS

I do not know the cross reference but DO NOT GET THE CHAMPIONS!!! They are probably the worst plug made for any kind of engine!

650's run warm anyway, so anything you can do to lower temp will make the engine last longer, mine seems to run a little better with the colder plug's.
