Heres an interesting question. On my '14 E350 cpe, the V6 is non turbo and only the passanger side of the engine has the air intake/filter so the drivers side air intake over the radiator area has a cap on the back which blocks any incoming air from the engine compartment. Would there be any advantages or disadvantages to removing this back cover to let some air flow into the engine compartment, for maybe additional cooling.

Leave it alone, it was designed for maximum air efficiency and intake silence.
