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.
Coils lose peak performance over time. You don't need to wait for a misfire to replace it. If the mileage is high, might as well do it at the same time as plugs.
