I still have the foam inside the air tunnel. It's fixed with steel clips. Is it not better to remove it ? Afraid there is rust building up underneath. What is the purpose of this foam? Noise reduction or dust catcher ?

Insulation both temp and noise.

I removed mine from the 712 as it was in terrible shape.
It was fairly easy to remove using a Heat Gun, spatula, and some patience.

I ended up applying a Noise deadening material that you can roll on or brush
apply, takes several applications to get a 4mm to 5mm overall thickness. This
product has rust inhibitors, is high temp, and water proof. It's a Polymer base.
My wind tunnel ended up rust free.

Here's a link to the product I used as an FYI

Does anyone know if there's a replacement material for the original that's closer to the foam type material?

I used 1/2" Dynaliner and it worked very well. I made cardboard templates to get the correct sizes for the pieces before applying it.
