Default Re: What spark plugs are you currently using?

I have used Champion C-4 with good results . The Champion C-4 plugs haven't been offered in many years . I like the look of the two piece Champion spark plugs. Most comment on the two piece plugs and think that they are original . There is a huge difference in the price of of The Champion 3- X and C-4 spark plugs . The C-4 plugs don't seem to be too cold and run clean in the model A's that I use them in. I sometimes buy new old stock C-4 spark plugs when I can find them . Champion W-18 spark plugs are readily available and are thought to be the same heat range as the original 3X but aren't two piece spark plugs like the 3-X .
