I think that the main slot needs to be a bit taller before it could ever really be functional as a scoop. An extra 1/2 in might be all thats needed. Then there is the whole issue of not having any room behind it to put any plumbing.
But if you open it up it might do a bit to help keep the engine cool.
Note, if I've gotten any facts wrong in the above, just ignore any points I made with them

WE DO NOT TALK ABOUT FUTURE PRODUCT PLANS PERIOD FbodFather
