    Spark Plugs

    I have two 2006 Seadoo GTX. I've been getting the NGK NCPR8E with the stud exposed like it says in the manual. But i've been replacing these at least once or twice a year. How come these won't last very long? I know the skies run up to 4000 to 5000 rpm when above 35-50 mph. Does anyone know of a better plug and if i have to get the ones with the stud exposed? Because the sparks that i have are $5.00 a piece and thats really expensive for replacing almost every year.
    Thanks
    Ben

    I've been to advance but they NEVER have the plugs that have the stud exposed or an unscrew type they only have the non removable studs. Those won't work will they???

    NGK 4339 is the ones you want. Look on-line and see which store has them or order enough stuff and get free shipping to your house.

    IMO use a standard plug with a .020 to .025 gap the more boost the smaller gap
    I thought we used 10mm plugs not 12mm
