I found this by googling for "neoprene sheet"
Does anyone know the variables of specifications?
I replaced the neoprene with a 5" ID silicone coupler. Trimmed it to fit and I have a solid seal between the aluminum intake and the plenum. I used some silicon tape to increase the diameter of the aluminum intake, making it a snug fit. Hose clamp is used on the aluminum intake. There is no need to use the clamp on the plenum as the coupler form fits.
$17 on Amazon.

Looks like a good solution. Question, how flexible is that coupler? Reason I ask is I don't have a straight shot from the intake ring to the plenum inlet, they are offset by 3/4 inch or so. If these are rigid then they will not work for me, although the could work week for the smaller air intake connection. I'd like something a bit stiffer in that location.
That's a good question. It's a very short length on my RV6 and it is pretty much a straight shot into the plenum. It'll flex 1/2" or so, but not much.
