spark plugs

Those are a standard NGK plug available most anywhere. On engines with high compression, advanced timing ect. it becomes necissary to run colder plugs. Looking at your list of mods you are not at the point you need them yet, you will be just fine with standard B8ES or BR8ES.
 
i was just wondering beacuse at work we run them in our sleds (polaris 550) and theres boxes of them, what do i need to do to run these plugs?
shes getting a big tear down this winter
