    I raced with the iridiums and spun my v6 way past 8100 and they last forever. The spark is more reliable and you can run colder with iridium so I would say better. Would I use them in a ski where I am replacing plugs every year for good measure and ride all salt? Probably not. Will they have any downfall in your machine, no.

    Re: Iridium spark plugs

    I tried these and they fouled out in about 4 hours or so. They did improve idle but stock plugs are much more reliable.

    I ran them years ago, and they work well, but if they get wet, or any moisture on them at all, their done, and won't recover. The stockers are more durable when it comes to moisture, and usually recover.

    Not worth the extra money IMO.

    I usually wash the engine with water after each outing, perhaps by spraying the engine with a little water to get wet spark plugs?
    The ski boots perfectly and the engine does not make any strange noise

    Dont waste your money. Stock plugs are fine. Use the extra money to Burn more fuel and enjoy the day on the water.
