What is the stock spark plug? I know its kind of a dumb question but my buddie let my other buddie borrow his 98 AC 454 while he was on vacation and he fouled a plug, he's coming home this week and we'd like to at least have it running when he comes back.. I know its a very small plug, anybody know the NGK#'s?

 

The stocker is a CR6E, but Arctic Cat recomends a CR8E for warmer weather.

 

Thank you.
