I think I read somewhere that it is better to start lower. That's what I did and I saw an improvement in MPG. But I think putting a block on the upper grill would be more beneficial, that way would let air go over the car easier... well at least in my mind it makes sense haha. And on my car blocking the upper grill opening would be easier.
