    Cr9ek Spark Plug Question

    I've been reading on here that a bunch of people have switched to CR9EK spark plugs and i've got a couple of questions. First how do they seem to be holding up compared with the stockers? Second where did you get the screw on caps that go on the end of the plugs since they just some with the threaded end. thanks fellas

    they work fine, and cost sh.t loads less.
    just buy them and dont listen to all the hype about OEM plugs the best.

    Do they run them on their JE piston boats? I thought the 9K's are 1 mm deeper than OEM? Not sure if the JE's are a shallower or deeper piston? Do you know Dawson?
