Does anyone know the recommended spark plug gap for the OEM plugs (superseded)?

I've received the NGK (SILZKR8E9G) plugs which is equivalent to the Hyundai part number for the 2.0T engine on a 2012 and some other model years.

Out of the box, three of the plugs are gapped to 0.034, but one of them seems like it got bent/bumped, its gap is much smaller.

Just wondering if 0.034 is the proper gap I should use on these NGK (SILZKR8E9G) for a 2012 2.0T engine?

OK after combing the net I gapped all my new plugs to 0.030." From what I could find, the recommended gap for the OEM NGK (SILZKR8E9G) plugs is 0.7 - 0.8 mm (0.0276 - 0.0315"). This would correspond to OEM part number 18849-09085, as shown below on Kia Parts Accessories screenshot:
