wait wait what, im very confused now , i read here (http://www.lincolnvscadillac.com/fo...952-Spark-Plug-Gaps&highlight=spark+plugs+gap) .054inches which would be about 1.4mm , the NGKs Iridiums i got are pre gapped (i checked) to .054,
am i missing something
i wanna be able to do this myself , instead of taking it to a shop and get charged 200$
but if need be peace of mind is worth the $$
That link you linked is for the Mark VIII, for the LS it is 1.0
That gap is extremely important as Joe mentioned, to maximizing the life of your coils. Please gap them to 1.0 as Joe mentioned. No more, no less. If they are over gapped you will have to reduce the gap to 1.0 as I had to do. Doing this the way I did (at first) led me to bend 2 of the diodes rendering the plug useless. So be careful when reducing the gap.
