Default Proper spark plug gap for 3.0?

I'm finally doing the plugs on my 2004, and the sticker on the core support says the gap should be 1.37-1.45 mm, which should be .05 - .06", correct? When I picked up the plugs (Autolite APP104) at Napa, their receipt indicated a gap of .044", which should I go by? I'm leaning toward the sticker, since I need to gap them anyway, from the box they are .037".

the sticker is there for a reason. for proper performance, listen to it.

the gap given on auto parts stores receipts is usually a "common" number, such a .044".
As seen on the internets!
