I believe that the 8 is a hotter burning plug. It's harder to foul out - in case your bike runs rich or burns a little oil. Performance wise (if you're running a race bike), it MIGHT not be the optimal plug, but you can run it with no problems.

one temp range isn't going to make much of a difference if any at all unless you're running really high comp and race gas cams and stuff like that. i wouldn't worry about it but another tip is to go to an auto parts store for the plugs you'll save a good chunk of money. i usually have luck with advance
