Not even if you are using the Jacobs or any stong HEI coil, I am told No
No No. I don't know where this came into play but I am almost certain
they said do not use these. Or any other kind other than the regular
spark plug. You should consider replacement as directed by our manuals
too! I know some will say not true but I think this is a good way to
keep the ol girl running properly, especially if we are going up hills
and down hills etc. New plugs every 5K for me. See Ya Chuck
