Unless the plug was dropped on the floor you dont need to gap these kinds of plugs

[anrkizm95]

you need to gap them everytime.i pull plugs out everyday where another tech or owner didnt think they needed to be gapped.the gap on them ranges from 35-65 out of the box.

The same plug part numbers can be used for several applications and the gap is not the same for all applications. Sometimes you might need to change the gap, but use the right tool.

Yep that circle tool is old school.

I got a wire one in my toolbox my dad gave me. I got a bunch of random old tools like that from him. I tried to use a coolant tester that's probably 40 years old and when I squeezed the rubber bulb to suck up coolant the plastic shattered lol.
