I would gap to .022 on NGK 97506s next time. Also change out your coils while you are at it.

Make sure you also run fuel additive once in a while and use ethanol treatment every tank if you run full e85 some day…
There is absolutely no need to change coils unless needed. A bad coil is a bad coil.

Could be your intake; common problem on the aluminum intakes.

I would also assume plugs.
I don't have aluminum intakes, Eventuri. Pretty sure it's the plugs. Car has 12k miles, not that coils couldn't go bad, but doubtful.
