If you buy the "generics" they do not come pre-gapped. I would get the NGKs over the Densos. I got my NGKs from AutoZone, using the generic part number. I believe it cross references to the Cadillac ATS with the turbo 4cyl. You can either buy these pre-gapped from a vendor like Whoosh or Tune+ or Stratified, or gap them yourself. They do not come pre-gapped if you buy them as generics (e.g on Amazon or VatoZone or O'Reillys, etc).
