Not sure how the COBB SRI Box is designed but that opening in the front corner of the grill seems ideal for an inlet leading to the box and providing fresh intake air from the outside, almost like a ram air effect.
I also wonder if adding a small cooling fan to the side of the box would be a good way of keeping the idle intake air temps stable. I am sure that idea will be flamed but I am sure a small fan wired in would help a little bit
