Best spark plug for E85

I won't be able to run any multi-strap plugs. If the strap isn't between 11:00 and 1:00 the piston will tap the ground strap and close the gap. Maybe indexing isn't the right term.

Wow that's close. Indexing is the correct term and if things are that close you'll have to index them. Since all spark plug threads in the head vary on where they start you'll have to manually index them.
