Would it hurt/help to have an additional opening in the bottom of the stock air box (below the filter)?

I thought I read another thread where someone used the stock air box, drilled a 3" hole in the bottom and ran a 3" tube down below the box into the area around the fog light. This opened up the intake side of the box and brought in more cold air.

Would this help?

In addition, what about insulating the stock air box and tube leading to the MAF. Wouldn't this also help cool down the air temp?
