For a NA the ONLY plug choice you have are the OEM plugs.

I am running NGK V-Power plugs and it runs fine right now, Should I change them out for OEM plugs?

The NAs are a bit less fussy about the plugs, TTs are the ones that really suffer but ultimately yes. the OEM plugs are longer than any other on the market and designed specifically for the VG30DE, no other plug reaches as far inside the cylinder as the OEM units.
