I have repaired/replaced the deteriorated foam on the side panels using air conditioner weather seal foam, that I purchased from a local big box home improvement store. After cleaning off what was left of the old foam, I used a good brand spray adhesive Spray Contact Adhesive (http://m.homedepot.com/p/3M-Super-77-16-75-fl-oz-Multi-Purpose-Spray-Adhesive-77-24/100067550), sprayed on both the side panel surface and the foam's surface to bond the foam pieces to the side panels.
I used the 2.25" square stuff. Air Conditioner Weather Seal (http://www.frostking.com/air-conditioner-weatherseal/)
This repair was also covered in the past Old Foam Repair Post (http://www.fjowners.com/index.php?topic=12325.0) here, and others had their own repair methods and materials to contribute.
What's the purpose of those things? I removed mine to prevent the dust of it going in the air-box and never put any replacements.
I can only imagine that the foam helps reduce noise from the air box and possibly some vibration noise. I doubt anyone could tell the difference between an FJ with the foam and without. Both my FJs have been without the foam for longer than with so I don't worry about it. I like the induction sound of the pods when I twist the wrist, no need to hide that growl.
I love the sound of the intake with pod so much. I tend to slow down just so I can listen to it while accelerating again. :pardon:
I am thinking about covering mine with Dynomat Xtreme. It should handle the heat and eliminate any vibration/buzzing noise. I have used this on car stereo install and the stuff is amazing.

Not sure if either will like the heat much, but there's a competitive product to Dynamat called Damplifier Pro. I bought a bulk pack like this:

On the 240z I'm restoring I used it to sound deaden the roof, doors, rear quarters, etc... changing the harmonics of these big drums pays off enormously. Anyway, about 11 pounds of the stuff (1 pack) did the whole car and it sounds like a 911 when you shut the doors. I've done another Z with the Dynamat and it has not worked as well... also weighs 2X at least, maybe more. You might check it out.

Frank. Good find. Dynamat Xtreme is good for up to 300 degrees F from what I could find online. The Damplifier Pro you mentioned has a thicker foil layer and is advertised as being good for up to 450 degrees F. That should be more than enough. I haven't placed my order yet, so will give the Damplifier a shot.
Considering the ABS plastic this stuff is going on melts at around 221* F, it seems to have the proper heat resistance properties.
