Uneven accelaration at low rpm/partial throttle

New owner to this 5, used to have a mazdaspeed protege, and i have a question. This thing has about 77k miles, it seems to hesitate slightly when accelerating at low rpms, i wouldn't say its as bad as that 01-008-08 TSB mentions it, and the car seems to have a record of the ECU being reflashed, but sort of feels like maybe spark plugs have too big of gaps or the spark plug wires kind of old? But this thing has coils on top I'm imagining so probably not that issue.

Do spark plugs need to be replaced on these things under 100k miles?
