As to the proximity of the box to the filter, yes, ideally there'd be more clearance, and I considered that before starting. But the box does expand out a bit towards the back with a full inch of clearance on the back side. It's nearly all open on about 1/3 of the front face now, as well. The added length portion increases clearance up to a half inch all the way around on that end, and no, it's not actually touching anywhere. There's at least a quarter inch clearance between the box wall and the surface of the filter at the closest point near the top inner portion.
In any case, it definitely made a noticeable improvement. It's getting at least one more pound full boost and the filter minder only just budges now, where before it was pulling almost halfway down.
