    Removing Spark Plug Terminal Nuts

    I'm attempting to install new DCPR8E NKG spark plugs into my RXT. I've never changed the plugs on any vehicle of any type. Is there a special way to remove the "terminal nut" on the end of the plugs? I'm assuming it does come off, since the ones I pulled out don't have them.

    Thanks!

    Yes, 2 pairs of pliers. Hold the hex with one set, and twist the terminal off with the other.
    Should be easy as, and sometimes you can do by hand.

    Got'em, the pliers worked. Those things were actually on there quite snug... I couldn't screw'em off by hand so I was starting to wonder if they were really even supposed to come off.

    There is two part numbers for the DCPR8E 4179 the top does not screw off and cant be used. 4339 has the removable top and is what you need.

    Beerdart, There's only one part # DCPR8E is the part # The other #'s your posting 4339 is actually a stock #. I can't find the other stock # 4179. I want to know what is the difference aside from the tip learning curve

    True, either it is DCPR8E, or not. The Jammer could be right.

    I have never seen it on the NGK ones, but the other plug equiv's may well be different.

    Unless they are old/newer batches of course. Beer... you not been buying ones made in china have ya..!!!
