One of the (many) things I dislike is trying to nail a specific spark plug gap.
With this tool, you place the desired feeler gauge into the gap, and turn the small bolt to close the gap until it contacts the feeler gauge – once and done, no constant checking and tweaking. Much faster.
You can make this with almost any scrap metal, a hand drill and a grinder.
Oh shoot – I may need a longer bolt for the non-projected tip plugs….
