That would be my suggestion.

As mentioned earlier, the stock gap is .028, if the car is not stock then that value is irrelevant.

I personally run mine at .022 with no misfire at 35 psi on stock coils and NGK oem replacement wires.

I would suggest getting a set of feeler gauges, those round plug gauges are not that accurate, not a huge deal with lower boost but when you get up in the higher power levels you want to maintain consistency between cylinders
