Rich, as far as I know, the engine has had no complaints with this set-up. I suppose you could create some sort of elbow from the intake side of the air box to the radiator support for a "cold air" effect, if you wanted/needed to, but for my everyday driving, things are just fine. There seem to be no breathing restrictions with the box butted against the fender, and the holes provided by the factory stampings

It just occurred to me that your set-up came from an Izusu (?), so I don't know how your filter box is created. Mine is from the Tahoe, from which the engine came, and the side that butts against the fender has openings for inlet air. Is yours the same?
