It's NPT tapped hole , you can purchase an NPT plug with an Allen recess in it , go to your local Vatozone , Advance auto or the like and check the fashion performance aisle



I know where to get NPT plugs, but are you saying that I should just thread it in without tapping it first?

if it is a tapped hole already , which it should be , why would you feel the need to tap it ??? NPT is a TAPERED thread as stated above so you will see 2 different sizes in the hole ...
