I'll try to save you Tug, is the sleeve really needed? I mean, it's nice to direct the air but if the filter is pulling that hard the hole will allow air to go in, right? The critical part is the hole in the side of the air box.

Probably don't need the sleeve. I'll take pics tomorrow for you. A hard plastic tube would be better to ensure air is coming from the wheel well. In the end, you could drill 20-30 little 5/64 holes in the housing there by the V-10 fender inlet and get the same result. That is what I should have done.

I got you, Rich. Here are some photos of what I did with the fender opening intended for the 6.8L engines. The foam sleeve is wedged between the inside of the fender well and the AIS housing. It can't move. You just need to tailor the end of the sleeve to fit up against the housing. 90% of the air coming through that hole I cut must pass through the foam sleeve. This keeps most of the leaves and bugs out of the opening and from clogging up the filter.
The hole I cut is about 3" across and 2.5" from top to bottom. I used a Dremel.
This is the AIS filter after 20k miles. LOTS of life left in it. Just knock the bugs and other larger debris out at each oil change. Those who say the filters are expensive don't understand how long they last. The price is a wash compared to the 4 or 5 stock filters you would go through before replacing ONE of these.

Nicmike's photos prompted me to have another look at my mess, and I guess I hid the ugly part pretty efficiently. I just remember it being a disaster when looking at the outside of the housing (which is hidden, thankfully). Good thing I checked, I had to clean out all the wildlife (flock of moths) that the 38R sucked through the grill and up hard against the filter.
