Karbonius airbox issue, fix myself or ship back?

Was this air box delivered brand new to you with that gap?

Yes

Basic ABS plastis should be OK. Most sheets will come one side textured which will work great for bonding.

You mentioned a urethane adhesive, is this better than an Epoxy (Like JB plastic weld) because it will flex better and not potentially break?

Any product recommendations would be greatly appreciated, I am ordering this platic block to shape, bond.

Not an expert but I generally try to use a urethane adhesive when heat and thermal expansion is more of an issue. Epoxy is better for chemical resistance.

If I’m bonding two pieces of carbon peel ply (rough textured side) to peel ply side, I use epoxy

In this application, I think urethane will be better. Epoxy will also work.
