I had my front grill off the other day and I was shocked at how small those two little oval holes were that feed those big intake tubes. I think that there is room for improvement with just opening up those two front holes. They were in the very outside corners of our grills if any of you haven't seem them from the front before. If those opening could be brought inward just a bit, or opened up like a true 3" round opening, and then maybe a small deflector to feed the air from the grill openings, I think that would be helpful. Those tubes could also be replaced with 2.5-3" piping all the way to the splitter.

intenseblu,
What do you think of the openings in the grill? Do you think they are ample enough?
