The larger side of this grommet goes into the engine compartment side of the hole right? So its not sticking into the interior so much, even tho the 4/0 will still be a big protrusion but atleast it can bend a lil unlike the grommet.

Whichever side has an o ring is the side thats toward the engine bay. I think the nut side. Do both sides have an o ring?

The oring is removeable like a washer. I ended up doing it the way i mentioned, bulge on the exterior, nut on the interior
