Your 2nd stage mods, appear to me to be way over the top. If you don't reseal the Airaid cut away portion to the cowl venting you have cut away, you will actually loose any benefit you may have gained. And besides you will greatly raise the heat being allowed to surround the intake. Then there is the positive/ negative ambient air flow induced by the cooling fans that will impact how air actually flows under the hood. This may effect the cooling pull all the way to your intercooler and cause additional problems. Good luck here, but this is a case of bigger and more ain't better. Believe it or not Ford does do a pretty good job of engineering these things. Not saying they can't be improved somewhat, but this going the wrong direction fast....best regards Plum
