    Modding normal spark plugs to work better

    [size=99px]1)[/size] First get yourself a set fo cheap spark plugs.
    I prefer the autolites. At about $1.09 a pop,
    you can't go wrong....Get the proper heat range
    your vehicle.


    [size=99px]2)[/size]The next step is to open the gap....ALOT! As seen
    here in these two pictures. I used the "key ring hole"
    ....know by few as its actual name, the "gap opener".





    This is what your plugs should look like for the next step



    [size=99px]3)[/size]The next step of the mod is to grind down the
    point of the ground strap so that it is rounded, but be carful not to grind down the center electrode. You can use a vise and a hand-held file, a dremel and a smalle grinding stone, or what I used here:





    Grind the tip back so that it is rounded like this:




    [size=99px]4a)[/size] Next you want to use the other side of the grinder....the wire brush wheel.
    This will help get ride of the sharp burrs and make it easier up the road for a future step. The step is not 100% nessary it just
    speeds the next step up, if no bench grinder is available to you,
    you can skip to the next step.






    [size=99px]4b)[/size]Ok in this next step you are to take some
    220-320 grit sand paper and smooth out the strap. I double the
    paper over and hold each side...then just go back and forth
    and move arounfd in different directions. This step is similar to
    a shoe-shine shining a shoe








    [size=99px]5)[/size]The next step to this is to bend the ground staps back. I use the vise, I have pretty good control and the mechanical advantage of it makes it cake work. After you get the strap about to where its suppose to be, use your gapping tool to set the plugs at the desired gap.




    [size=99px]6)[/size]WHen its all done, the gound strap should only come over the center electode HALF WAY. The point of grinding the strap back is to get it out of the way fo the flame front. This will help direct the flame downward into the piston instead of outward to the sides.

    This is what the finished product should resemble:





    THE first 2 set of plugs you do should be on the old spark plugs. Get good at this before you move onto using new plugs.

    Wow, thinking this one needs to be removed. From 2006 no less, you would need a seance to find those pictures, that must be like three or four Sphere versions ago lol.

    IIRC, it is essentially moving the ground strap away from the center electrode
    maybe directly exposing it to the compresses air and fuel?

    i did this a couple times to keep plugs from fouling as quickly. HOWEVER, the vehicle would not go more than 25 miles before it burned so much oil the lifters were rattling

    unless you're driving a junkyard quality vehicle, unmolested plugs work just great

    You're so crazy! enough in a way that i'll probably say you destroyed me!

A Chevrolet 5.7-liter LS1 V8 with this much specific power (horsepower per cubic inch) would be making 2,137 hp
