im thinking about taking out them plastic covers and putting mesh in there like from a vrd grill or somthing maby just going to local hardware store and getting it and painting it black and sticking it in there for colder air flow for my soon to be in my hands injen(or takeda) intake. good idea or am i a idiot

 

It will pretty much do nothing except let water get in there, and more dirt. It will not give you anymore hp, just leave it

 

You could just route the air to your brakes...less chance of them warping during intense braking runs.

Otherwise it might not do anything. Once you are at speed the vacuum created after the under panels is great enough to suck all the air out of the car.

Do it if you want! Post pics too

 

probally gonna leave it

 

fig grilles makes those

 

i did it.. i am not sure it made and difference in HP but it sounds good
