fatter screws
I have an 03S with stock airbox,so I don't know if this would work for you,but I used larger diameter stainless steel sheet metal screws when mine stripped out.

Sounds that will work until those strip out, then I'll get bigger and bigger screws!
I'm taking my car for service today and I'll check to see if it's possible to buy a new base to the airbox. I didn't see it (or the airbox at all) on Real OEM. -

Just get yourself some bigger sheet metal screws and carefully thread them by hand. When you feel slight resistance and you see that the screws are bottomed out, stop tightening. The OEM ones get stripped when people try to over-tighten them.

Why use the box top at all?
The Alta seals against the bonnet anyway. -

Ahhhh........now I see. Stock air box was the clue, right?

I use a long 8-32 machine bolt and nut, place the nut on a strip of tape, screw the bolt through lid and bottom box until it barely exits, stick nut on bolt end and screw, remove tape when threaded, hold nut while tightening.

There are a lot of games you can play...
you can fill it with epoxy and drill a pilot hole. There's the toothpic, there's Keiths suggestion. The screws are thread forming screws for plastic.
I've got an extra base, I think. PM me if you want it for cheap.
