Searching, oval, rounded edge, ABS or.. inserts to insert in the bumper cover for more FMIC air

These work amazingly well for replacing the fog lights and hooking up brake cooling hoses, I was going to use them for that purpose but the mid opening below the bumper, above the TR splitter, funnels into an area I can tap into for brake cooling, which turned out to be very cool

And I get to keep the fog lights and looking at some very nice complete bolt in LED units...

But I want something like the above in an oval shape to maximize the flow of air to the IC.

Ever seen anything like it?

Thanks

Thanks, interesting parts, never searched for bumper ports before

I will have to set the bumper cover back on and get more exacting measurements.

I want it as subtle as possible if I do this and rounded over inlets are far better aero wise.

Much appreciated
