I WANT to run a filter even at the track, but the better intake manifold I'd like to use is taller than the one that I can actually fit under my T/A hood scoop and won't allow for an adequately sized filter.

Not sure if running a smaller (more restrictive) filter setup on the street, and switching out to something more of a "bird and rock catcher" screen only at the track, is a viable approach... or if that's simply fooling myself.
