Hey all you S.T. owners I been reading and watching videos about this B12 Chemtool . I just wonder how effective it may be on removing spark plug carbon because my 07 4.6 is noted for spark plug breakage on original plugs which is what I still have in my ST. Will it help eliminate the chance of breakage ? What do you think. My truck is running great but some say get them boogers out even so. Thanks .
B-12 Chemtool have you used it?
