Spark Plug Gap

Did some searching in the forums but came up empty handed...

I got myself some new plugs and coils.

Before putting them in I wanted to double check the spark plug gap.

Should I even bother with this extra step? I haven't seen anything in the forums where people talk about checking the gap before installing the plugs.

The plugs I bought are Motorcraft SP-479

That's what I was thinking. These plugs didn't come with the paper ring that normally would protect them from landing on the electrode

I believe that they come gapped at .54

Good thing the tool I specifically went out and bought yesterday doesn't have the marking I need.

It only gives me options for .044/0.50/0.60
