    Just wondering what higher performance spark plug will work with a 80cc=66cc 2 stroke engine and a good plug boot?

    I was looking at a V-POWER NGK-BKR6E-11 not sure if that would work..Thanks a bunch

    i just bought two B6HS', 3 feet of 7mm copper cored, non-resistant plug wire, 2 boots and end terminals (i don't have 2 cylinders, i just figured i'd stock up) for 8 bucks from my local supplier.

    haven't put it on yet, but i'm sure it's the hot ticket...

    What does hotter or colder mean for a spark plug? Does the engine actually run hotter/colder? Is the spark greater?

    Hotter or colder refers to the heat range of the plug. This is how the plug transfers heat to the head to rid itself of heat. A colder plug may foul more easily, while a hotter plug can cause detonation (not likely in our engines) and other problems. Best to stay somewhere in the middle of the range for your engine.
    No difference in spark generally.

    I'll bring this question up again. I just purchased the NGK BKR6E-11 as well. Before I open the package I'd like to know that it will work properly if anyone knows. Canadian Tire didn't carry the BP6HS.

    Canadian Tire couldn't tell you the difference? I guess that's no surprise. Auto parts store counter men aren't what they used to be.

    I've seen a list on here before of spark plugs that can be used on 2 strokes. I don't remember if it was under 2 strokes, general discussions or trouble shooting though.
