cold air vs air lid?
If you have a Firebird, you can cut openings in the hood brace behind the dual inlets in the bumper, and that will feed cold air directly to the air filter.

It didn't make the car run any hotter or anything like that, and it seems to work, according to IAT datalogs. FWIW, I also have a lid.
After you have the lid, the FTRA (Fast Toys Ram Air Kit) is a very worthwhile mod and will also help improve your fuel economy which means the kit will eventually pay for itself.
