Newb question on spark plugs

Are the stock plugs made by AC Delco? Just trying to figure out if these are the originals that I pulled from my LQ4. Thanks.

Normally, OEM is AC Delco but in late 1998 there was a strike and resulting shortage of AC Delco plugs. My then brand new 99 TA came from the factory with NGK Platinum plugs. I bought the car new off the show room floor so imagine the surprise when we did the first plug change on my TA with only 4000 miles on it and found eight NGK's.

My 2000 had Denso from the factory.
