Came up with an easy to make adapter that could suck air from behind my manifold shield if I put spacers in to increase the clearances. The straight sides will make this a breeze on my sheet metal brake. It's hard to make out, but the bottom edge of the adapter would have several hooks (just bend back some of the sheet metal) to latch onto the edge of the manifold shield. It's basically a funnel, trading width for height as it goes towards the ducting. On the end near the duct I could have a sliding panel over a hole to allow in colder air to limit maximum temperature. It'd just be a piece of sheet metal with a bent edge you can grab, hinging on a rivet. Maybe a locking wing nut too. I didn't bother to draw it. My drawing's dimensions aren't reliable, it's just the gist (it's drawn way too big). There are plenty of attachment points to support the far end of the adapter, and taking it off should be straightforward.
Figured out how to get the spacers behind the shield: use magnets to keep them from falling off the bolts as I install it. I guess I could use masking tape or some glue as well, but I don't want that stuff burning away, and I've already got the magnets.
