Replacement air scoops for undertray

[LAP1DOUG]

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.

Great idea!
