Are these genuine AC Delco plugs?

Don't waste your money on these plugs. I ordered those and the gap was different on all 8 plugs. Platinum plugs should be pre gapped, these were not. I sent them back and bought the irodium plugs which is recommended for the GM 5.3L and the 6.0L engines

Will they fit a 2003 gmc yukon denali 6.0 engine, n what's the gap?

Yes they fit. They should be received pre-gapped and you should not try to change them as they damage easily.
