You can also consider making them from light weight plastic. Check out Foam Core PVC or Foam PVC sheet from Tapp plastics, 1/8". It is very light, easy to cut with saw or shears, heat with a heat gun to bend. If they hit something, they will just shear off without breaking anything under your car or cutting a tire. And they won't be a real hazard for anyone behind you.
Make them real short, then extend them with sheet rubber and pop rivets.

I was a bit surprised Walter's tag line wasn't, "It's all breaking".

I've always used my name online. No reason to hide. I've made mistakes (plenty) no need to hide behind a screen name

I built an air dam for my Mustang with some 1/4" foam PVC and a heat gun.
I plan to build one for my Box someday.

I can see (now) how it sounded like it was aimed at you, it was actually a general statement
The stang setup looks good!!

Update on the home made air scoops:
They worked fine for a few hundred miles of street use, and even over some normal size speed bumps. Then I ran over a cone at an autocross, and it sort of mashed them in (very light gauge aluminum) but didn't tear up anything else.
I have a track day coming up in a week, so, now I get to make some more, which is a 30 min. job, or order some of the rubber ones. If you don't autocross, then no worries

It would be interesting to measure airflow with the aluminum versus rubber just insde the inlet. I'll bet there is a much higher flow with the aluminum than the rubber due to the stiffness of the aluminum.

Someone said that an overheating transmission can make you loose a gear?
Is that just for the automatic transmissions or does that happen on manual transmissions as well?
I never noticed these scoops on my car so they might be missing.
I like the aluminum scoop idea but since I have a 3D Printer perhaps I should make a pair out of ABS plastic. In ABS they would disintegrate on impact and won't end up a sharp edged flying object at the auto-x.

Does anyone have a photo of these on the car?
Just out of interest, If the diy ones are the same shape with the same intake area, I would think the airflow would be the same. What if the front of the scoops were widened but kept at the same depth, it would surely increase the air volume and speed which would increase the cooling effect. Would they fit? Is there any way to fit some type of heat sink to the gearbox to increase the surface area to dramatically increase the cooling? What about spraying the gearbox black to increase the heat transfer more?
Just some thoughts without actually seeing the area that the scoops fit on to. Not had the boxster on the axle stands yet.
