    spark plugs?

    My local autoparts store told me that there was no difference between a marine grade plug and an auto plug, except the auto one would foul out faster. Is this correct? I'm using NGK br8es-11, he said NGK br8es are auto plugs and would work fine?

    I have attached a chart bellow. The BR8ES should work but, you might have to change the gap.

    B= 14mm
    R= Resistor
    8= Heat Rating
    E= 19mm Thread Reach
    S= Standard 2.5mm dia. electrode
    -
    11= 1.1mm Gap (.044)

    I hope this helps

    I allways check the gap on my br8es-11 and i get 39 not 44 sometimes closer to 40 but never 44 I have also run the br9es in my ski but the comp is 138 not the stock 120 with 150 i think you should run the br9es.
