Unused Air intake
Heres an interesting question. On my '14 E350 , 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.

No. Airflow through the engine bay is carefully controlled, that's why there's a ton of baffles and seals around the radiator and front end, all air coming in goes through the cooling package, then over the engine and down and out the bottom of the car. If you open up more holes in the front of the car, the only thing you do is increase drag. Will be negligible, but it won't have any positive effect.

negative air pockets are engineered into all modern cars to essentially induce a vacuum in the engine bay at speed. This serves suck hot air out of the engine. Positive pressure air pockets are located immediately in front of the radiator and (often) at the base of the windscreen. Negative air pockets are controlled by use of baffles and cowls (as mentioned above) to reduce turbulence below the car and recycle air inside the engine bay. Even small changes to these, especially in higher engineered cars will have negative effects. So remember put your skid plates back on and replace/repair broken plastics.

Thanks for the thoughts, Guys. It seem that someone by now would have come up with an add on intake Y pipe connection to connect this opening to the air box side intake pipe for more air increase volume...more has to be better, right?

+1. I think that make a great product. Any DIY ideas?

Adding my two bucks. In the newer cars even the pitch of the grill slats are important for air delivery to the intake runners. We have all paid quite dearly for this engineering so keep it in mind before making changes.
