Have you considered getting an intake blockoff plate thing? Then you would be able to utilize both inlets.
The problem with that is it blocks off the flow of air to the engine and the little oil cooler on that side. I'm thinking under the hood temps would rise with that being blocked.
The plate is made for the GTE...14.lt engine with hybrid electrics...which also has the full length under engine bay aero tray....so that gets way hotter...
