Can someone help me identify which EGR port plug size (honda part number would be nice) is needed to plug the EGR port on the very end of the runner? I have circled the hole in red in the attached picture. It is not the same size as the plugs for the main EGR ports on the intake runners which require honda part number 17199-PT3-AHM. The port on the end is larger than the ports on the runners. Thank you for the help.

I am considering drilling and tapping to put a plug in but would rather use the right plug from Honda if it exists.

You do not touch that plug at all, only the 6 plugs that face upward.

I've learned that the hard way (too late)!
I'm tapping 1/4" NPT and putting in a brass hex pipe plug, we'll see how that goes.
