Spark plugs in a alum block...
I have a small 4 cylender, I have heard rumours of putting in 2, 3, 4 pronged sparks will cause excesive heat and possibly cause smaller alum blocked engines to over heat easily, is that true? what performance plug would be suggested for such engine, probly NGK ofcourse but what pronged is what im wondering...
