    2003 250 Plug

    F250FPLSTR

    2003 250 Rude motor. The plug chart calls for QC12PEP or QC10WEP. Which of these would be the better plug to run. Getting ready to de-carb and change plugs. Thanks in advance for any info.

    The QC10WEP will last longer, they are what I use!

    I have heard of some runing the QC8WEP like the 250HO uses. Is there an advantage to using them and if so would something else need to be changed?

    Tom,
    Index them and put the 10's in gap them at .028 tight. Don't put them in until after the decarb, buy 7 or 8 you'll use them.
