The reason behind my idea is based on the K.I.S.S. principle. All that would need to be done is lift one end of the whole insert about 2-1/2" and fill in the gaps on the sides, add a filler under the scoop to deter water and debris entry and provide attachment points. Not trying to reinvent the wheel here, or anything fancy, just simple and effective. The individual could easily make their own underhood baffle plate to direct airflow where they want it.
